Answer:
the annual interest return rate is .025 i believe.
Step-by-step explanation:
after 6 months the money increased by 5.75 bucks.
the 6 month return rate was .0175, so double that to get the annual rate.
80 as a product of prime numbers can be expressed as 2×2×2×2×5
18 Weeks
$39.50=17 + (5*x)
$39.50-17=17-17 + (5*x)
$22.5/5=(5*x)/5
It will take 4.5 months to save up. If each month has 4 weeks it will take 18 weeks
r=-1/5
