Answer:

The correct option is B. 14.55 %

Step-by-step explanation:

Cost price of the new dishwater = $320

Down payment made by Noel = $20

Amount which is left to be paid = 320 - 20 = $300

Number of monthly payment = 10

Amount paid for each monthly payment = $34

Total amount paid by Noel = Down payment + Total monthly payment

                                             = 20 + 34 × 10

                                             = $360

Interest paid by Noel = 360 - 320

                                     = $40

Principal value of the interest = $300

Time = monthly payment months + 1 ( This is the month in down payment is made)

Time = 11 months

\bf\text{Time = }\frac{11}{12}\text{ years}

\text{Now, Rate = }\frac{interest\times 100}{Principal\times \frac{11}{12}}\\\\\implies Rate = 14.55\%

Actual yearly interest paid by Noel = 14.55 %

Therefore, The correct option is B. 14.55 %

How to simplify 9+5(4x+4)
RoseWind [281]
Use PEMDAS. Parenthesis, Exponents, Multiply, Divide, Addition, Subtraction.
So, you'd distribute 5 into the parenthesis, leaving you with 9+20x+20, then add like terms. 20x+29

A number is increased by 50% and then another 25%. By how much is it increased in total?
blsea [12.9K]

Answer:

87.5 percent

Step-by-step explanation:

when you have to increase a number by 50 percent you are multiplying it by 1.5

later when you increase the number by 25 percent you multiply it by 1.25

you can multiply 1.5 by 1.25 to get your answer

1.5 * 1.25 is 1.875

so the percent increase is 87.5 percent
