Zach invested $1500. he earned 23.2% on his investment. determine how much money he has now.

To figure out 23.2%, first figure out how much 1% is by dividing 1500 divided by 100=15

Next, multiply the 15(1%) by the 23.2% to figure out how much that is.
23.2 x 15 = 348

Now, you have to add thr investment ($348) to his originsl amount of money ($1500).
$1500 + $348 = $1848

Zach now has $1848

Number nine is f(x)= 40x : ) hoped i ya
