Question

2. A watch cost $ 48 more than a clock. The clock of the clock is 4/7 the cost of the watch. Find the total cost of the 2 items.

Answer 1

3 s + 5( s-15) = 101
8 s - 75 = 101
8 s = 176
s = 22

Answer 2

c = 4 w/7
w = c + 48
w = 4 w / 7 + 48
7 w = 4 w + 336
3 w = 336
w = 112
c = 4 * 112 / 7 = 64
