PSLESimon and Tom shared the total cost of a present. Simon paid $18 less than
27 of the cost of the present. Tom paid $78. How much did the present cost?
Simon |
Tom |
Total |
2 u - 18 |
5 u + 18 = 78 |
7 u |
Total amount paid = 7 u
Amount that Simon paid = 2 u - 18
Amount that Tom paid = 5 u + 18 = 78
5 u = 78 - 18 = 60
1 u = 60 ÷ 5 = 12
Cost of the present
= 7 u
= 7 x 12
= $84
Answer(s): $84
