Answer:
Yes, she will have $1.96 left
Step-by-step explanation:
Initial cost : $60
Discount : 25%=0.25
Calculating discount : 60 * 0.25 = 15
Calculating cost after discount : 60-15 = 45
Sales tax : 6.75%=0.0675
Calculating sales tax : 45 * 0.0675 = 3.0375≈$3.04
Calculating final cost : 45+ 3.04 = $48.04
Can she buy the printer : 50 - 48.04= $1.96
Answer : yes
Answer:
The answer to this question can be defined as follows:
Step-by-step explanation:
please find attached file.
P = A(1+i)ⁿ, where:
A= initial value
I = interest in %
n= period of compound investment.
However, if the interest is paid twice a year, that means you have to divide the interest by 2 and the period becomes twice n
P = 875(1+9.5%/2)⁵ˣ²
P = 875(1+4.75%)¹⁰
P =875( 1.0475)¹⁰
P = $1,391.7
