Robert bought $1.60 worth of stamps with 20 coins all in nickels and dimes. how many nickels and dimes did he use?

1 answer:

3 0

Nickels are 5 cents, and dimes are 10 cents.
(By luck..) eventually you can have 12 dimes, meaning you have 120 cents, or $1.20 ... 20-12=8.. meaning you used 12 dimes and are missing 8 more coins. which means you can have 8 nickels which is 40 cents. 120+40=160 cents or $1.60
Hope this helped.

A bike rental company charges $60 for the first hour, and $25 for each additional hour. Michael wants to spend less than $200 on

-Dominant- [34]

It is d. The h is the amount of hours and this must be paired with 25 because that is the rate do you can eliminate b and c. It is not a because that is making it so the cost is above 200 when you are trying to keep it below that

Well knowing that it’s 5 1/4 and the cost of paint is 13.99, I’m going to assume to multiply by the given product which is 13.99 by one quarter (which is 25)
