Question 1127683
either you don't know your own email address or you mis-spelled it or it's a phony. I don't care, here's your answer:
p + n + q = 151
and:
n+1 = q
3n = p
0.01p + 0.05n + 0.25q = 10.15
now substitute for pennies and quarters:
0.01(3n) + 0.05n + 0.25(n+1) = 10.15
0.03n + 0.05n + 0.25n + 0.25 = 10.15
0.33n = 9.90
n = 30 Sandra has 30 nickels
Quarters = n+1 = 30 + 1 = 31
Pennies = 3n = 30(3) = 90
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Check:
30(0.05) + 31(0.25) + 90(0.01) = 10.15 Correct
