Question

The calf on Mr.Green's farm weighs about 180 pounds. The calf gains about 64 ounces of weight each day. About how much will the calf weigh after four weeks

Answer 1

The calf starts at 180 pounds.

16 ounces = 1 pound
28 days = 4 weeks

The calf will gain:
64 * 28 days = 1792 ounces
1792 ounces = 112 pounds

So the original weight + the amount gained:
180 + 112 = 292 pounds
