+86 Josh has 90% more pennies than quarters. His total is $8.07. How many quarters does he have?
+128406 Let the number of quarters = N.....then, the number of pennies = N + .90N = 1.90N
And the number of quarters* time their value plus the number of pennies times their value gives the total value of all the coins......so.......
N (25) + 1.90N (1) = 807 simplify
25N + 1.90N = 807
26.90N = 807 divide both sides by 26.90
N = 807/26.90 = 30
This is the number of quarters
And the number of pennies = 1.90(30) = 57
