Answer

Estimate 42 gallons Exact $41 \frac{5}{8}$ gallons

Work Step by Step

Estimate $148 - 69 - 37 = 42$ Exact $147 \frac{1}{2} - 68 \frac{1}{2} - 37 \frac{3}{8}$ = $147 \frac{1}{2} - 68 \frac{1}{2} - 37 \frac{3}{8}$ = $79 - 37 \frac{3}{8}$ = $78 \frac{8}{8} - 37 \frac{3}{8}$ = $41 \frac{5}{8}$
