Question

HELP OMG BRO IVE BEEN ASKING THIS FOR SO LONG SOMEONE IM BEGGING U HELP MEEE

Josh received a gift card of $70 for a pizza restaurant. The restaurant charges $20 per pizza. Jessica received a gift card of $60 for a different pizza restaurant. The restaurant charges $15 per pizza.
Let x be the number of pizzas purchased.


Write an equation to show when the two cards would have the same amount of money left on them.

Answer 1

70 - 20x = 60 - 15x

Solution:

x = 2

Explanation:

The problem said to let x = number of pizzas purchased.

So at Josh's place 1 pizza is 20, 2 is 40, 3 is 60, etc. The mathy way to write is 20x... <<that's 20 times the number of pizzas. It tells us the dollar amount spent on pizzas. His gift card is $70. We'll subtract what he spends on pizzas from his total original amount 70.

70 - 2x

For Jessica, its the same logic, but her gift card is $60 and the pizzas are 15 each. Total spent on pizzas is 15x. Her balance will be

60 - 15x

The question wants us to find out when these to people have the same balance of their card.

70 - 20x = 60 - 15x

This is what is asked for in the question. Below is how to solve it (don't know if you need this)

minus 60 from both sides

10 - 20x = -15x

Add 20x to both sides.

10 = 5x

Divide by 5

2 = x

This means when Josh and Jess have each bought TWO pizzas, they will both have $30 left on each of their cards.
