Question

jacob went to the gas station with $17.70. He bought a drink for $2.90, and he wanted to spend the rest of his money on a bag of chips for his friend which costs $1.85 each. What is the maximum number of bags of chips that he can buy? Define a variable then write and solve an inequality.

Answer 1

He can buy 8 bags of chips.

Explanation:

first create a equation:

drink's cost + bag of chip's cost(number of chips) = total

2.9 + 1.85x = 17.7

17.7 is the total, 2.9 is the cost of the drink, 1.85 is the cost of a bag of chips, and x is the number of chips.

Solve for x:

2.9 + 1.85x = 17.7

-2.9 -2.9

1.85x = 14.8

1.85 1.85

x = 8

Check:

12.9 + 1.85(8) = 17.7

12.9 + 14.8 = 17.7

17.7 = 17.7
