First to answer correctly gets (i acendentally marked as ssthis is math)james has dimes and quarters saved up in his change jar. hr has a total of 162 coins totaling $31.20 what is the total amount james has in quarters? a. $10.00b. $6.20c.$15.50d.$25.00

D. $25

Explanation:

From the information given, you can write the following equations:

d+q=162

0.10d+0.25q= 31.20

First, you have to isolate one of the variables in the first equation:

d=162-q

Then, you have to replace d in the second equation and solve to find the quantity of quarters, q:

0.10(162-q)+0.25q= 31.20

16.2-0.10q+0.25q= 31.20

0.15q= 15

q= 100

d=162-100= 62

Now, that the quatities of dimes and quarters were found, you can determine the amount you have in dimes and quarters:

Amount in quarters= 0.25*100= $25

Amount in dimes= 0.10*62= $6.2
