65+90=155-180
Answer:
$18500 at 6% and $28500 at 8%
Step-by-step explanation:
Let x represent the amount invested at 6%. Then x+10000 is the amount invested at 8%. The total income from the two investments is the sum of the products of the amount invested and the interest rate:
x·6% +(x+10000)·8% = 3390
0.14x + 800 = 3390 . . . . . . . . collect terms
0.14x = 2590 . . . . . . . . . . . . . .subtract 800
2590/0.14 = x = 18500 . . . . . divide by the coefficient of x
Sue has invested $18500 at 6% and $28500 at 8%.
Divide 74 into 4 and 6
74/4 = 18,5
74/6=12,33
so if you buy in bags of 4 you need 19 bags, which costs 5 x 19 = $95
if you buy in bags of 6 you need 13 bags, which costs 7 x 13 = $91
Buying in bags of 6 costs less.
