Question

brandon and steve went to the store. they bought bags of chips, pretzels, and gummy bears.They bought three times as many bags of pretzels as bags of chips, and two fewer bags of gummy bears than 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.

Answer 1

Vicky, if x is chips, then pretzels is 3x and gummy bears is 3x - 2.

 

Putting them all together...

 

x + 3x + 3x - 2

 

Remember that x is like 1x...

 

7x - 2 is our answer.
