katen-ka-za [31]

Answer:

Savings on electricity per year by brand B = 114.3 - 104.76 = $9.54

Step-by-step explanation:

Ms. Wang is shopping for a new refrigerator. Brand A costs $569 and uses 635 kilowatt-hours per year. Brand B costs $647 and uses 582 kilowatt-hours per year.

Let's assume he buys brand B, so he already has a loss over the price of the commodity that is , loss = 647 - 569 =$78

Cost of electricity = $0.18

Now in the case of electricity,

spending on Brand A = 635\times 0.18 = $114.3

spending on Brand B = 582\times 0.18 = $104.76

Savings on electricity per year by brand B = 114.3 - 104.76 = $9.54

gavin deposited $1500 into his savings account that is compounded quarterly at an interest rate of 1.5%. How munch money will ga
creativ13 [48]

<u>Answer:</u>

The money will gavin have after 5 years is 1616.59$

<u>Explanation:</u>

We know that compound interest is given by  

A=P\left(1+\frac{r}{n}\right)^{n t}

          Where A = final amount

       P = Principal amount = $1500 (given)

r  = interest rate = 1.5% = 0.015

n = no. of times interest applied per time period = given quarterly = 4

t = time period = 5 years  

    So,

A=1500\left(1+\frac{0.015}{4}\right)^{4 \times 5}

1500\left(1+\frac{0.015}{4}\right)^{20}

 = 1616.59$ which is the money will gavin have after 5 years
