1) Javier has 24 coins that are all dimes and quarters.
The value of the coins is $3.75. How many dimes and
how many quarters does Javier have?
A. d+q = 24
.25d +.107 = 3.75

B. d+q = 3.75
.10d +.25q = 3.75

C. d+q = 24
.10d + .25q = 3.75

D. .100 +.259 = 24

.10d + .25q = 3.75

Answer:

I am pretty sure the answer is C.

Step-by-step explanation:

Since the total amount of quarters and dimes Javier has is 24, we can use the variables d (representing the dimes) and q (representing the quarters) and come up with d + q = 24 for the first part.

for the second part, we know that every dime is worth 10 cents, or, .10 and every quarter is worth 25 cents , or .25 so for the second part, we can come up with the equation .10d + .25q = $3.75 .

i hope this helps (:
