Ineed in my math homework only 4 questions
2. kateri saves her quarters and dimes. she plans to exchange the coins for paper money when the total value equals $10.
(use this information to solve the following parts)
a. how many coins does she need to make $10 if all the coins are quarters? if all the coins are dimes?
b. what equation relates the number of quarters x and the number of dimes y to the goal of $10.
c. use the answers from part (a) to you draw a graph showing the solutions to the equation.
d. use the graph to find the five combinations of the dimes and quarters that will allow kateri to reach her goal.

A: If all coins are quarters, she'd require 40 quarters. That is because 4 quarters equal a dollar, so I multiplied that by 10 to get the value of 10 dollars. If all coins are dimes, the amount of dimes would be 100, because 10 dimes equal a dollar, so I multiplied that by 10 as well.

B: An equation that'd probably work is 0.25x + 0.10y = $10

I've used those values because x representing quarters meant I had to multiply by it's value, .25 cents. Same goes for dimes.

C, I don't know how to show a graph here, so I'm going to assume you know how to graph.

D:  Also requires the graph, but I can think of x = 20, y = 50. You can do it!
