Write one or two equations to represent the situation below. Solve the equation(s). Show all your work.
A collection of dimes and quarters totals 72 coins. Together the dimes and quarters are equal to $11.70. How many of each coin are in the collection?
2 and 6 tenths?
Can you show me the equations and how you got that plz
I can't help with the other problem, Danny. I'm clueless at how to solve it without looking at my old textbooks.
This one, however, is relatively simple.
If d is dimes and q is quarters, write what you know:
d + q = 72
The dimes and quarters have to equal 72 coins)
0.10(d) + 0.25(q) = $11.70
(You need to factor in the value of each coin when figuring out how to get to the total.)
I hope that helps you! My class is over and I won't be at the computer anymore tonight.
