<h3>What is Algebra?</h3>

Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.

Jill invested $500 in an account with a compound interest rate of 6%.

Cheryl invests $600 in an account with a compound interest rate of 4%.

The number of years each doubles their money. Using the relation of 72.

$\rm t = \dfrac{72}{r}$

where r is the interest rate and t be the time

The time for the Jill will be

$\rm t = \dfrac{72}{6}\\\\t = 12\\$

The time for the Cheryl will be

$\rm t = \dfrac{72}{4}\\\\t = 18\\$

bogdanovich [222]

Cherry pie is $ C.
Pumpkin pie is $ P.

C + 9P =60 -------> C=60 - 9P
11C+4P = 90

11(60 - 9P) +4P=90
660 - 99P + 4P = 90
-95P = -570
P =570/95 = 6
P=6
C=60-9*P=60 - 9*6= 60-54=6
C=6

Answer: 1 cherry pie -$6, 1 pumpkin pie - $6.

Check:
11C+4P = 90 , 11*6 +4*6 =90, 66+24=90, 90=90 True
