Answer:
Alex baked 9 cherry pies
Step-by-step explanation:
apple : blueberry : cherry = 1:4:3
apple + blueberry + cherry = 24
1 part: 24 / ( 1+4+3) = 24 / 8 = 3

check: apple = 3 x 1 = 3
blueberry: 3 x 4 = 12
12 + 3 + 9 = 24

<u><em>Steps to answering this question </em></u>
- Determine the total number of comics bought. This can be done by dividing the total amount spent on comics by the unit price of a comic
- Determine the selling price of the comic
- multiply the amount of comics bought by the selling price
the total number of comics bought = total amount spent on comics / per unit price of comics
$20.16 / $0.72 = 28
selling price = 0.72 - $0.20 = $0.52
Total amount received = selling price x total comics bought
$0.52 x 28 = $14.56
Answer:
1260.04
Step-by-step explanation:
The formula for compound interest is:
A = P(1+
where A is the final amount, P is the initial principal balance, r is the interest rate, n is the number of times interest applied per time period and t is the number of time periods elapsed. Since the deposit was compounded annually, just like the interest, we can omit the n in the equation.
Applying the formula to question:
800(1+
= 1260.04 (rounded off to nearest cent since it's money)
