Answer: She invested $34100 at 10% and $68200 at 6%.
Steps:
Let x1 be the amount invested at 6%, x2 the amount at 10%
After one year the simple interest is amount * (interest rate).
The total interest after one year:
7502 = x1 * 0.06 + x2 * 0.10
and we know that x1 = 2*x2
7502 = 2* x2 * 0.06 + x2 * 0.10 = 0.22 * x2
x2 = 34100
x1 = 2*34100=68200
Answer:
The amount of butter, sugar and flour does Clifford need is 2.5 cups flour, 3.75 cups sugar and 1.25 butter
Explanation:
Consider the number of cup of flour used to be x
According to question,
Recipe calls for 1.5 times as much flour as sugar
Sugar =
Sugar = 1.5x
Butter = ½ x = 0.5x
According to question,
Flour + Sugar + Butter = 7.5
x + 1.5x + 0.5x = 7.5
3x = 7.5
x = 2.5
Sugar = 1.5x = 1.5(2.5) = 3.75
Butter = 0.5(2.5) = 1.25
Clifford need is 2.5 cups flour, 3.75 cups sugar and 1.25 cups butter
