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%.
Answer:
Step-by-step explanation:
b = pints of blueberries
c = pints of cherry tomatoes
3b + 2c = 28
2b = c
First, substitute 2b into the c of the first equation.
3b + 2(2b) = 28
3b + 4b = 28
7b = 28
b = 4
Then, substitute 4 into the b of the second equation.
2(4) = c
c = 8
Then, substitute both values into the first equation to check.
3(4) + 2(8) = 28
12 + 16 = 28
