Half a watermelon and half a pound of cherries cost $3.09.
A whole watermelon and two pounds of cherries cost $8.16.
Find the cost for a pound of cherries and the cost for a watermelon.
Back
Answer
0.5w + 0.5c = 3.09
1w + 2c = 8.16
-1w - 1c = -6.18
1w + 2c = 8.16
c = 1.98
w + 2c = 8.16
w + 2(1.98) = 8.16
w + 3.96 = 8.16
w = 4.20
A pound of cherries costs $1.98
and a watermelon costs $4.20.
