here is the question: A man has $2.25 in quarters and nickels. He has 9 more nickels than quarters. How many nickels and quarters does he have. (How do i set up the chart and solve it?)
Let number of quarters =x
Number of nickels =x+9
x*0.25 +(x+9)*0.05 =2.25
x =1.80/0.30= 6
Number of quarters =6 ; value 1.50
Number of nickels =15 ; value =0.75
Total value =2.25
