You are debating about whether to buy a new computer for $800.00 or a refurbished computer with the same equipment for $640.00.

If a savings account earns 4.5% APR interest, how much do you really save with a refurbished computer if you put the difference into the savings account for a year?

Firstly, we need to find the difference between the two. First, we have to take a grand total of $800 and subtract it by the used/refurbished total of $640. After we subtract the two, we would get $160. Next, we want to multiply the $160 by our interest rate. In this case, the interest rate is 4.5%. To convert this to a decimal, we do 0.045. When we multiply $160 by 0.045 we get $7.20. So the final total would be $167.20.

Therefore, you would get $7.20 out of interest!

Jimmy can run 3.5 miles in 20 minutes. how far can ne run in one hour and ten minutes?
prisoha [69]

Hello There!

Before we start, I am going to divide 3.5 by 2 because then we can multiply by 7 to see how far Jimmy can run in 70 minutes.

Jimmy can run 1.75 miles in 10 minutes.

To find out how many miles he can run in 70 minutes, we just multiply 1.75 by 7 and we get a product of 12.25

Jimmy Can Run 12.25 Miles In 70 Minutes
