Answer:
61% increase
Step-by-step explanation:
Product of two numbers = x * y = xy
(x + 15%) * (y + 40%)
Due to the fact that x and y are variables, we can add the percents to them
1.15x * 1.4y
Multiply
1.61xy
Calculate percent increase
1.61xy (new amount) - xy (original amount)
------------------------------------------------------------ * 100
xy (original amount)
Simplify
.61xy
--------- * 100 = 61%
xy
61% increase
