Ahmad spends $16 each time he travels the toll roads. He started the month with $224 in his toll road account. The amount, A (in dollars), that he has left in the account after t trips on the toll roads is given by the following function.

A (t) = 224 - 16t

Answer the following questions.

a. How much money does Ahmad have left in the account after 11 trips on the toll roads?

b. How many trips on the toll roads can he take until his account is empty?

Part a

[tex]A(11)=224-16(11)=\boxed{\$48}[/tex]

Part b

[tex]A(t)=0\\\\224-16t=0\\\\t=\frac{224}{16}\\\\t=\boxed{14 \text{ trips}}[/tex]

a) The amount of **money **does Ahmad have left in the account after 11 **trips **on the toll roads is $ 48

b) The number of **trips **on the toll roads can he take until his account is empty is 14 trips

**Equations **are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an **equation**.

Given data ,

Let the **equation **be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A ( t ) = 224 - 16t , where t is the number of trips

a)

The amount of **money **does Ahmad have left in the account after 11 **trips **on the toll roads be P

Substituting the value of t = 11 in the equation , we get

A ( 11 ) = 224 - 16 ( 11 )

A ( 11 ) = 224 - 176

A ( 11 ) = $ 48

So , The amount of **money **does Ahmad have left in the account after 11 **trips **on the toll roads is $ 48

b)

The **number **of **trips **on the toll roads can he take until his account is empty be n

when A ( t ) = 0

224 - 16t = 0

Adding 16t on both sides of the equation , we get

224 = 16t

Divide by 16 on both sides , we get

t = 14 trips

Variables are the letters that represent a number. So, it would be the ones bolded here: 3**x**=12 and **y**=1/2**x**-6

If we have half a **dollar**, three **quarters,** eight **dimes**, six **nickels**, and nine **pennies** , then we **altogether** have $2.44 .

In the question ,

it is given that

we have half a **dollar** ,

we have , **three quarters **means

we have 75 cents

and 75 cents = $0.75

we have 8 **dimes** ,

we know that 1 dime [tex]=[/tex] 10 cents

so , 8 dimes = 80 cents

and 80 cents = $0.80

we have six **nickels**,

we know that 20 nickels = $1

so , 1 nickel = $1/20

and 6 nickel = $ 6/20 = $0.30

we have nine **pennies** ,

we know that 100 pennies = $1

So ,1 Pennie = $1/100

and 9 pennies = $ 9/100 = $0.09

Which statement allows the line q and p are parallel ?

According to the converse of corresponding angles theorem, the statement that allows Carmen to conclude that lines p and q are **parallel **is: ∠2 ≅ ∠6.

A **transversal** is a line that crosses two straight lines. For example, line t is a **transversal** that crosses the lines p and q in the given diagram above.

**Parallel** lines are lines that do not meet each other at any point and are of equal distant to each other.

When a **transversal** intersects two **parallel **lines, they form angle pairs. One of such angle pairs is, corresponding angles, which are always congruent to each other.

Thus, if corresponding angles are formed and are equal to each other, then the lines they lie on must be **parallel **lines based on the corresponding angles converse theorem.

Angles 2 and 6 are corresponding angles that are formed by the **transversal **that intersects lines q and p. If they are congruent angles, then the lines are **parallel**.

Therefore, Carmen can use the statement, ∠2 ≅ ∠6 to show that lines q and p are **parallel**.
