Question

Jamie buys 3 snacks and 2 bottles of juice. Each snack costs $0.75, and each bottle of juice costs j dollars. The total cost of the snacks and bottles of juice is $6.75. Which of the following equations could be used to find the cost of a bottle of juice, in dollars?

Answer 1

2.25+2j=6.75

That is the answer I got

Answer 2

Answer is 3(.75) + 2j = $6.75 is the equation

Step by step

Since you didn’t give options I will give you my equation.

3 snacks * .75 + 2 juice * x unknown $ = 6.75

3(.75) + 2j = $6.75 is the equation

Solve

2.25 + 2j = 6.75

Subtract 2.25 from both sides to isolate j

2.25 - 2.25 + 2j = 6.75 - 2.25

2j = 4.50

Divide both sides by 2 to solve for j

j = $2.25
