Answer:
Both of them correct.
$21.945
They have enough money to purchase the book
Step-by-step explanation:
Oscar takes 30% of the normal price and subtracts it from the normal price. Out of 100% price he takes 30% so the result is: 100-30%= 70% of the normal price. Oscar's first step has the same result as Kim.
Oscar takes 10% of the discounted price (70%) and adds it back. The price will become 70% + 10%*70%= 77% of original price. Kim multiplies the discounted price with 110%, so the price will be: 70% * 110%= 77%. Both also give the same result.
The final price is 77% of the original, it will be: $28.50* 77%= $21.945
Both of them can buy the book
Answer:
$221.44
Step-by-step explanation:
As the bank charges a <em>monthly </em>interest, we cannot calculate a simple or compound interest over the 8 month period. As the balance will decrease each month as Kylie makes payments, the interest applied each month will also decrease. Therefore, we have to use:
<u>Monthly Payment Formula</u>

where:
- PMT = monthly payment
- P = loan amount
- i = interest rate per month (in decimal form)
- n = term of the loan (in months)
Given:
- P = $1,700
- i = 0.925% = 0.00925
- n = 8 months
Substituting the given values into the formula and solving:

Therefore, the monthly payment to the nearest dollar will be $221.44
