Answer:
Cost of the binder = $5
Cost of the highlighter = $2.5
Cost of the folder = $2
Step-by-step explanation:
Let
Cost of the binder = x
Cost of the highlighter = 1/2x
Cost of the folder = x - 3
Total cost = $9.50
Total cost = Cost of the binder + Cost of the highlighter + Cost of the folder
9.50 = (x) + (1/2x) + (x-3)
9.50 = x + 1/2x + x - 3
9.50 + 3 = x + 1/2x + x
12.50 = 2x + 1/2x
12.50 = 2 1/2x
12.50 = 5/2x
x = 12.50 ÷ 5/2
= 12.50 × 2/5
= 25/5
x = $5
Cost of the binder = x = $5
Cost of the highlighter = 1/2x = 1/2*6 = $2.5
Cost of the folder = x - 3
= 5 - 3 = $2
