Answer: $120
Step-by-step explanation:
Assume the original price is x.
He sold the scooter for $130 and this was $50 less than 1.5 times what he paid for it.
Relevant formula is therefore:
1.5x - 50 = 130
1.5x = 130 + 50
x = 180/1.5
x = $120

Answer:
the answer depends on which type of interest we use:
- simple interest rate = 24%
- compound interest rate = 26.82%
Step-by-step explanation:
the interest rate paid for holding the cards one month 1/50 or 2%.
to convert 2% monthly interest rate to a simple annual rate:
monthly rate x 12 months = 2% x 12 = 24%
now to convert 2% monthly interest rate to an annual rate (using compound interest):
- = (1 + r)ⁿ - 1
- = (1 + 0.02)¹² - 1 = 1.2682 - 1 = 0.2682 or 26.82%
in compound interest, earned interest earns even more interest by itself besides the interest earned by the principal.
