Answer:
not really sure for number one
1. 1.56y × 3.9x
2. 4.8x + 9.6y
FUTURE VALUE = PRESENT VALUE * (1 + r)^t
PV = 220,000
r = 3%
t = 7 years
FV = 220,000 * (1 + 3%)^7
FV = 220,000 * (1.03)^7
FV = 220,000 * 1.22987386542487
FV = 270,572.25
Answer: 25
Step-by-step explanation:
Plug in x to the expression.

When there is the same base of exponents is being multiplied the exponents add together and the base stays the same.
So this simplifies to,
.
This then solves to 25.
