Answer:
amount of interest = 52.5
amount at the end of the period = 1052.5
Step-by-step explanation:
use the formula for simple interest
PRT/100
P is the principle
R is the rate of interest charged
T is the Time taken
18 months = 1 years 6 months ( 1.5 years)
1000 * 3.5 * 1.5 = 5250
5250/100 = 52.5
the amount of interest = <u>52.5</u>
the amount she will have at the end of the period
= 1000 +52.5
= <u>1052.5</u>
Did you mean this? <span>3^2x+1=3^x+5 => 3^(2x+1) = 3^(x+5)? If so, then 2x+1 is necessarily equal to x+5, so that 2x+1=x+5. Thus, x = 4 (answer).
Those parentheses are not optional; they must be part of your problem statement and solution.</span>
