Martha invested a principal amount of $15,000 into a savings account that earns simple interest at a rate 4.5% per year. how much money will she earn in interest over 6 years?

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
