8. Aaron and Zelly want to rent a tandem bike so that

they can ride together. The rental for a tandem bike is

$18.50 per hour plus $3 for each helmet. Aaron and

Zelly have $80 to spend on the bike rental. Which

equation can be used to find h, the number of hours

they can rent a tandem bike? (hint: if you do not know

what a tandem bike is, you need to look it up!)

80 = 6h + 18.50

80 = 18.50h + 3

80 = 18.50h + 6

80 = 3h + 18.50

Answer:

[tex]80 = 18.50h + 6[/tex]

Step-by-step explanation:

Given

[tex]Amount = \$80[/tex]

[tex]Rent = \$18.50[/tex] per hour

[tex]Helmet = \$3.0[/tex]

[tex]Individuals =2[/tex]

Required

Derive an expression for the scenario

A tandem bike allows 2 individuals to ride on it at a time.

So, they will only pay for one rental fee because both can ride on it at the same time.

However, they need to get separate helmets.

For Helmets, they will spend:

[tex]\$3 * 2 =\$ 6[/tex]

For Rental, they will spend

[tex]\$18.50 * h = \$18.50h[/tex] for h hours.

[tex]Total = Rentals + Helmets[/tex]

[tex]Total = 18.50h + 6[/tex]

Recall that they have just $80 to spend

So, substitute 80 for total

[tex]80 = 18.50h + 6[/tex]

Hence, option C answers the question.
