Question

Martin has a combination of 33 quarters and dimes worth a total of $6. Which system of linear equations can be used to find the number of quarters, q, and the number of dimes, d, Martin has?


A) q + d = 6
25q + 10d = 33


B) q + d = 6
0.25q + 0.1d = 33


C) q + d = 33
25q + 10d = 6


D) q + d = 33
0.25q + 0.1d = 6

Answer 1

Answer:

q + d = 33  0.25q + 0.1d = 6

Answer 2

Answer: D) . $q+d=33$

$0.25q+0.1d=6$

Step-by-step explanation:

We know that $1 = 4 quarters

⇒ 1 quarter = $\frac{1}{4}=\ 0.25$

$1 = 10 dimes

1 dime =$\frac{1}{10}=\ 0.1$

Let 'q' be the number of quarters and 'd' be the number of dimes.

Since, Martin has a combination of 33 quarters and dimes worth a total of $6.

$q+d=33$

$0.25q+0.1d=6$
