Question

Jamil always throws loose change into a pencil holder on his desk and takes it out every two weeks. This time it is all nickels and dimes. There are 7 times as many dimes as nickels, and the value of the dimes is $2.60 more than the value of the nickels. How many nickels and dimes does Jamil have? a. 28 nickels and 4 dimes b. 3 nickels and 21 dimes c. 4 nickels and 28 dimes d. 5 nickels and 35 dimes

Answer 1

d = 7n and 10d - 260 = 5n are your 2 equations.

Answer 2

The first equation says that the # of dimes is 7 times the # of nickels. The second equation equates the monetary value of the two types of coins.

Answer 3

I have no clue what you're saying... but my answer is C. (:

Answer 4

You can substitute the first equation into the second and have an equation in one variable, "n". Once you simplify the resulting equation, you will be able to tell whether or not your answer is correct. If you show some work, I can see where you are going with your logic and then I can tell you if you are right or wrong.
