Problem
After five years of earning interest at an annual rate of 3%, an investment has earned $950 in interest. To the nearest whole dollar, determine the amount of the initial investment.
Result
The initial investment was $6,333.
Solution
P = I/ i · t
P = 950/ 0.03 · 5
P = 6,333.333
Answer:
1, 2, 4, 5, 8, 10, 20, 40
Step-by-step explanation:
These number can all divide 40
3 hundreds + 7 hundreds = 1 thousand
300 + 700 = 1000
She spent $310 on the singing camp.
MY WORK:
I multiplied $86.50*20 because $86.50 is the amount she deposited for 20 months. $86.50*20=$1740.00
Then I multiplied $24.50*20 because she spent $24.50 for 20 months. $24.50*20= $490.00
Then I subtracted $1740.00-$490.00 because she spent $490 out of her bank account. $1740.00-$490.00=$1240.00
Finally, because its 1/4 of her money, I divided $1240.00 by 4. $1240 divided by 4= $310
Hope this helps!!
