Answer:
D. c/7
Step-by-step explanation:
An algebraic expression refers to the equation. In the question, it says to divide a number (c) by seven, giving you c/7
The formula of the Simple Interest is:
I=PRT
P for Principle Amount ($1200)
R for Rate (5%=

= 0.05)
T for Time in years (4 years)
I = 1200 × 0.05 × 4
= $240
Add the interest to the principle amount to check the balance
$1200 + $240 = $1440
Parentheses are used to identify which numbers you should add,multiply .ect first. So If i had
12-(3+1)=x
then you would want to solve 3+1 before you subtract 12.
