Problema Solution
Jennifer went on a shopping spree, spending a total of $107 on a skirt, a sweater, and a pair of shoes. The cost of the sweater was 7/6 of the cost of the skirt. The shoes cost $12 more than the skirt. Find the cost of each item.
Answer provided by our tutors
let cost of skirt item = x
sweateritem = y
shoe item = z
y = 7/6 x
z = x + 12
x+y+z = 107
x+7/6 x +x +12=107
19/6 x = 95
x = 30
y= 35
z = 42
