A. d + q = 15
0.10d + 0.25q = 2.85

B. d + q = 2.85
0.10d + 0.25q = 15

C. d + q = 15
10d + 25q = 2.85

D. d + q = 2.85

Question

Mikayla has 15 coins made up of all dimes and quarters worth a total of $2.85.
d = number of dimes, q = number of quarters
Which system of equations represents this word problem?

	A.	d + q = 15
0.10d + 0.25q = 2.85


 

 	B.	d + q = 2.85
0.10d + 0.25q = 15

 	C.	d + q = 15
10d + 25q = 2.85

 	D.	d + q = 2.85
10d + 25q = 15

anonymous · Answer

D+q=15 ( the sum of both must be 15)
.10d+.25q=2.85 ( the value of which coin time their quantity gives you the total value)
