Answer:
x=16
Step-by-step explanation:
From the Free Response Row,
For the Total Time(in minutes) column
Since x=55-3m and x=8(15-m)
Therefore:
55-3m =8(15-m)
55-3m=120-8m
Collect like terms
-3m+8m=120-55
5m=65
Divide both sides by 5
m=13
Therefore:
x=55-3m=55-3(13)=55-39
x=16

Answer:
a) amount in the bank after 7 years if interest is compounded quarterly is $6,605
b) amount in the bank after 7 years if interest is compounded quarterly is $6,612.57
Step-by-step explanation:
We are given:
Principal Amount P= 5000
Rate r= 4% = 0.04
time t = 7 years
The formula used is: 
where A is future value, P is principal amount, r is rate, n is compounded value and t is time
a) Find the amount in the bank after 7 years if interest is compounded quarterly?
If interest is compounded quarterly then n = 4
Using values given in question and finding A

So, amount in the bank after 7 years if interest is compounded quarterly is $6,605
b) Find the amount in the bank after 7 years if interest is compounded monthly?
If interest is compounded quarterly then n = 12
Using values given in question and finding A

So, amount in the bank after 7 years if interest is compounded quarterly is $6,612.57
