I believe it’s 72 I hope it’s right
Convert the two fractions into simpler fractions: 3 2/5 --> 17/5 and 4 1/5 --> 21/5. Notice the the denominators are identical, so we simply add the numerators: (17 + 21)/5 = 38/5 = 7 3/5.
There is an easier way to do this, this is just the most clear way of seeing everything.
The total number of acorn squash that the farmer brought to the market = 80
Percentage of acorn squash was less when the day ended = 35%
Then
The amount by which the
number of acorn squash decreased at the end of the day = (35/100) * 80
= 280/10
= 28
Then
The number of acorn squash left with the farmer = 80 - 28
= 52
So from the above deduction, we can easily conclude that the farmer was left with 52 acorn squash at the end of the day.
