Step-by-step explanation:
Answer: the cost would be the same for 12 shirts.
Step-by-step explanation:
Let x represent the number of shirts for which the cost would be the same.
One company charges $9.65 per shirt plus a setup fee of $43. This means that total amount charged for x shirts would be
9.65x + 43
Another company charges $8.40 per shirt plus a $58 fee. This means that total amount charged for x shirts would be
8.4x + 58
For both costs to be the same, the number of shirts would be
9.65x + 43 = 8.4x + 58
9.65x - 8.4x = 58 - 43
1.25x = 15
x = 15/1.25 = 12
Exponential
The first year, he would earn 8% interest on the $400 deposited, so he'd have $432. The next year, he would earn 8% interest on the interest earned the previous year in addition to the amount deposited, so he'd have $466.56.
His bank balance would follow the compound interest equation which is exponential.
= 400 × 1.08^t
where t is the number of years since the deposit
The value of the investment of $2500 for 3 years will be $3703.86.
<h3>What is compound interest?</h3>
Compound interest is applicable when there will be a change in principle amount after the given time period.
For instance, if you give someone $500 at a 10% yearly rate, $500 is considered your primary sum. After a year, the interest will be $50, making the principle amount $550. Moving forward, the interest will be $550 rather than $500.
Given,
Principle amount (P) = $2500
Rate of interest (R) = 14%.
Time period (T) = 3 years.
Compound interest formula
A = P
So,
A = 2500[1 + 14/100]³
A = $3703.86
Hence the investment of $2500 at a rate of 14% for 3 years will be $3703.86.
