A coin collection contains d dimes and q quarters worth a total of $50. Which equation models this information?

d + q = 50

10d + 25q = 50

0.1d + 0.25q = 50

0.01d + 0.25q = 50

0.1d + 0.25q = 50

Step-by-step explanation:

dimes are worth 10 cents so it's 0.1 and d represents the unknown amount

quarters are worth 25 cents so it's 0.25 and q represents the unknown amount

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

y=20x
