Problema Solution
The price of one brand of athletic shoes is $5 more than another brand. If the prices of the two pairs of shoes add to$230, how much does each pair cost.
Answer provided by our tutors
x = y+5
x+y = 230
y+5+y =230
2y + 5 = 230
2y = 225
y = 112.5
x = y+5 = 112.5 + 5 = 117.5
so one pair costs $117.50 and the other costs $112.50
