Question 552489: Arnel invest some of his savings at 4 percent per year and an equal amount at 7 percent per year.His income totals ₱33 000 a year.How much did Rico invest at each rate? Answer by JBarnum(2146) (Show Source):
You can put this solution on YOUR website! x = the amont invested in each interest rate
the amount(x) + the interest rate(.04x) added to the amount(x)+the interest rate (.07x)=total for the year(30000)
check
.04x=568.72
568.72+14218.01
14786.73
and
.7x=995.26
995.26+14218.01
15213.27
so 14786.73+15213.27=30,000
correct
