Answer:
$213.41
Step-by-step explanation:
To do this question, you have to use the formula for compound interest:
A=P(1+r/n)^nt
The A is the final amount of money you make which is $237.60. P is your initial amount that you are trying to solve for. R is the rate of interest. However, for r you have to convert the percent into a decimal so divide 1.2 by 100, which would be 0.012. N is the number of times it is compounded annually which is once. And finally, t is the number of years taken, which is 9. If you substitute the numbers into the equation it should look like this:
237.60=P(1+0.012/1)^1*9
If you solve for P, you should get $213.41.
Hope this helps :)
Answer:
Step-by-step explanation:
Let red candy weighs r and blue candy weighs b
<u>Total weight is 7 pounds:</u>
<u>Red costs $1.5 per pound, blue costs $2 per pound and total cost is $12</u>
We have two equations.
<u>Solve by elimination, double the first equation and subtract the second equation from the first:</u>
- 2r + 2b = 14
- 1.5r + 2b = 12
<u>Subtract and solve for r:</u>
- 2r - 1.5r = 14 - 12
- 0.5r = 2
- r = 4
<u>Find b using the first equation:</u>
<u>The answer is:</u>
- Mike had 4 pounds of red and 3 pounds of blue candies.
