Question

Ashanti and Maria went to the store to buy snacks for their back-to-school party. They bought bags of chips, pretzels, and nachos. They bought three times as many bags of pretzels as bags of chips, and two fewer bags of nachos than bags of pretzels. If x represents the number of bags of chips they bought, express, in terms of x, how many bags of snacks they bought in all.

(Theres two more problems in a picture, you don’t have to answer all three tho but if you do it i will love you forever :( )

Answer 1

Hey there!

For the first one:

Chips: x

Pretzels: 3x

Nachos: 3x-2

Total snacks: x+3x+3x-2=7x-2

For the second one:

In the equation, 150+5d, 150 represents the starting amount of money, in this case, 150 dollars. 5d means that for every day, five dollars get put into his account.

For the third one:

In this equation, 1.50 represents to initial fee, and 2.25m represents the cost per mile. Dividing by 2 gives us what each person in the cab pays.

Let me know if this helps :)
