Question

To get ready for the new school year, Mrs. James took her two children shopping. Jim selected a coat that cost

$42.78 and two pairs of jeans. His sister Jamie found a pair of boots for $60.58. The total cost of the items before tax
was exactly $148. If Jim's two pairs of jeans were the same price, how much did one pair cost?

Answer 1

$22.32

Explanation:

42.78 (for the coat) + 60.58(for the boots) + 2j (for the two pairs of jeans) = 148(the total)

42.78 + 60.58+ 2j= 148

subtract the cost of the coat and the jeans

2j=44.64

divide by two

j=22.32

the jeans cost $22.32

Answer 2

22.32

Explanation:

coat + 2 pairs of jeans + boots = 148

42.78 + 2j + 60.58 = 148

Combine like terms

103.36 + 2j = 148

Subtract 103.36 from each side

103.36 - 103.36 + 2j = 148-103.36

2j = 44.64

Divide by 2

2j/2 = 44.64/2

j =22.32
