A farmer has 120
bushels of corn

bushels each day. After 7

Part 1
Write a signed number representing the change in the total number of bushels the farmer has for sale.
To find the change in the total number of bushels the farmer has for sale, we need to subtract the amount of corn he sells in 7 days from the initial amount of corn he had.
The amount of corn he sells in 7 days can be calculated by multiplying the average amount of corn he sells each day (14 and one fourth bushels) by 7.
14 and one fourth bushels can be written as 14.25 bushels.
So, the amount of corn he sells in 7 days is 14.25 bushels/day * 7 days = 99.75 bushels.
To find the change in the total number of bushels the farmer has for sale, we subtract the amount of corn he sells (99.75 bushels) from the initial amount of corn he had (120 bushels).
Change in total number of bushels = Initial amount of corn - Amount of corn sold
Change in total number of bushels = 120 bushels - 99.75 bushels
Change in total number of bushels = 20.25 bushels
Therefore, the signed number representing the change in the total number of bushels the farmer has for sale is -20.25 bushels.
To find the change in the total number of bushels the farmer has for sale, we need to subtract the amount sold from the total number of bushels.
The farmer sells an average of 14 and one-fourth bushels each day, which can be written as 14 + 1/4 = 14.25 bushels per day.
After 7 days, the total number of bushels sold is 7 * 14.25 = 99.75 bushels.
To find the change in the total number of bushels the farmer has for sale, we subtract the amount sold from the initial total of 120 bushels:
Change = 120 - 99.75 = 20.25
Therefore, the change in the total number of bushels the farmer has for sale at the farmer's market is 20.25 bushels.
