Answer:
B. 152 + 7
Step-by-step explanation:
(8x + 16) + (7x - 9)
8x + 16 + 7x - 9
15x + 16 - 9
15x + 7
None of these options have this answer, so we see A and B:
A. x + 7
B. 152 + 7
It can't be A because we have 15x and A is x + 7
By process of elimination we have B. 152 + 7
x = 10 and 2/15
15-6.9=8.1
8.1 x 3.9= 31.59
$31.59 is your answer
hope this helps :)

Complete question is;
If Pablo invests $4200 for 3 years and earns $630
A) what is the simple interest rate?
B) Pablo’s goal is to have $5000 after 4 years. Is it possible with a rate of 6%? Explain.
Answer:
A) Rate = 5%
B) Yes, it is possible for him to earn $5000 after 4 years with an interest rate of 6%
Step-by-step explanation:
A) Formula for interest is;
i = PRT
We are given;
i = 630
P = 4200
T = 3
Making R the subject;
R = i/PT
R = 630/(4200 × 3)
R = 0.05
This is 5%
B) Formula for value of principal after interest period is;
A = P(1 + RT)
P = 4200
R = 6% = 0.06
T = 4 years
Thus;
A = 4200(1 + (0.06 × 4))
A = $5208
Thus, it is possible for him to earn $5000 after 4 years with an interest rate of 6%
