1. Which of the following is the sale price for an item with an original price of $9.99

after it has been discounted 35%

2. Joe borrowed 1500$ from the bank at a rate of 8% simple interest per year. Over the course of three years, how much interest did he pay?

Step-by-step explanation:

1) The initial price of the item is $9.99. The initial price was reduced by 35%. This means that the amount by which the initial price was reduced would be

30/100 * 9.99 = 0.35 * 9.99 = $3.4965

Therefore the sale price would be

9.99 - 3.4965 = $6.4935

2) The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

From the information given

T = 3 years

P = $1500

R = 8%

Therefore

I = (1500 * 8 * 3) / 100

I = 36000/100

I = $360

Sale Price = $ 15.37

Interest = $ 360 for three years

Step-by-step explanation:

Discounted Price = $9.99

Sale Price = $ 9.99*100/65 = $ 15.37

2. Simple Interest = Principal * time * rate = $1500 * 3 * 8/100=$ 360
