Martha's total earnings is the sum of her fixed pay pay day and the extra she gains based on the number of toys she sold. Her total earnings may be expressed as,
44 + 2n
Since she desires to earn $80 or more, the inequality is expressed as
44 + 2n ≥ 80
Solving for n from the inequality,
n ≥18
Thus, the answer is the first choice.
7/11 is the answer? I believe so
Answer:
$5659.11
Step-by-step explanation:
We are given;
- Time of loan maturity is 5 years
- Rate of compound interest is 7% compounded quarterly
- Principal amount of the car is $4000
We are required to determine the total amount he paid at the end of 5 years..
The concept being tested is compound interest;
We are going to use the compound interest formula;
Amount = P(1+r/100)^n
Where P is the the principal amount
r is the rate of interest
n is the interest periods
In this case;
n = (5 × 4) = 20
r = 7 ÷ 4 = 1.75 ( as the money was compounded quarterly)
Thus;
Amount =$ 4000 ( 1 + 1.75)^20
= $4000 (1.0175)^20
= $5659.11
Therefore, the money that Joe will have paid at the end of 5 years is $5659.11
