(1 point) do this step by step

Answer 1

1) Let x = dollars per hour mowing lawns.
2) Earnings = (hours mowing)(rate mowing) + (hours car wash)(rate car wash): 22x + 4(10).
3) Set equal to total: 22x + 40 = 392.
4) Subtract 40: 22x = 352.
5) Divide by 22: x = 352/22 = 16.

You make $16 per hour mowing lawns.
