Given:
3 pepperoni pizza for every 2 cheese pizzas sold
12 cheese pizzas sold.

This is a proportion problem:

3 : 2 = x : 12

a : b = c : d  where ad = bc

a = 3 ; b = 2 ; c = x ; d = 12

3 * 12 = 2 * x
36 = 2x
36/2 = 2x/2
18 = x

18 pepperoni pizzas are sold during the 20 minute period.

an electronics store had 182 video games. if they put them on shelves with 24 on each shelf, about how many shelves would they n
GalinKa [24]
182 games 24 on each shelf basicaaly x shelves is more than or equal to 182 games 1 shelf=24 x times 24>182 divide both sides by 24 x>7 and 4/24 x has to be a whole number since you can't have fractional shelves you have to have more shelves since less shelves won't allow you to carry all of them round up 7 and something rounded u is 8

 8 shelves (if you are a weird store that has fractional shelves then the answer is 7 and 1/6 shelves)

A bike shop rents bikes for $4.50 per hour, plus a $7.50 insurance charge. For how many hours can Peter rent a bike if he has $3
Mandarinka [93]

Answer:

With $30, Peter can afford 5 hours

Step-by-step explanation:

Given

Insurance Charge = $7.5

Charges = $4.5 per hour

Required

Determine the number of hours $30 can afford

First, we need to determine the equation.

<em>Total Charges = Charges per hour + Insurance Charge</em>

Substitute values for Charges per hour and Insurance Charge

Total Charges = 4.5 per hour + 7.5

Let the number of hours be n;

So,

Total Charges = 4.5n + 7.5

To calculate Peter's; substitute 30 for total charges

30 = 4.5n + 7.5

Subtract 7.5 from both sides

4.5n = 30 - 7.5

4.5n = 22.5

Divide both sides by 4.5

n = \frac{22.5}{4.5}

n = 5

Hence;

<em>With $30, Peter can afford 5 hours</em>
