In Winter, the price of apples suddenly went up by $0.75 per pound. Sam bought 3 pounds of apples at the new price for a total of $5.88. Write an equation to determine the original price per pound.
Let x be the original price per pound of apples.
After the price increase of $0.75 per pound, the new price per pound would be x + 0.75.
Sam bought 3 pounds of apples at the new price for a total of $5.88, so we can write the equation:
3(x + 0.75) = 5.88
Solve for x:
3x + 2.25 = 5.88
3x = 3.63
x = 3.63 / 3
x = 1.21
Therefore, the original price per pound of apples was $1.21.
