d)480
for the !

Option A is the correct answer.

Step-by-step explanation:

Let the work plow a field be x.

Annmarie can plow a field in 240 minutes.

   Rate at which Annmarie can plow

Gladys can plow a field 80 minutes faster

Time taken by Gladys = 240 - 80 = 160 minutes.

   Rate at which Gladys can plow

If they combine time taken to plow

Option A is the correct answer.

total = principal × ( 1 + rate ) ^ years

total = 600 * (1.04)^5

total = 729.99

answer is c
