Answer:

Step-by-step explanation:

In the real world amortization mortgage loans have equal monthly installments paid for the life of the loan.

The monthly installments are found by

I=P\left(\frac{r-1}{r^n-1}+(r-1)\right)\\ \\ r=1+(r/12),\ n=12(30)=360\\ \\ I=550000\left(\frac{.00167}{1.00167^{360}-1}+.00167\right)\\ \\ I=\$ 2032.91\\ \\ \text{If we subtract the total paid over thirty years minus the principal we get the total interest paid.}\\ \\ 360(2032.91)-550000=$181846.56

Anna has $430. She wants to buy a phone that costs $275. Anna will also have to pay a sales tax of 7%.
ki77a [65]
19.25 (tax)
294.25 (total price)
135.75 (money left)

REASONING:

In this word problem it says Anna has 430 dollars. The phone costs 275 dollars. It also says that when she buys the phone, she will have to pay a tax of 7%.

To find how much tax she will pay, we must do [275] x [0.07]

After inputting this into a calculator, you will get 19.25 (tax)


To find the total price, all you have to do is add 19.25 to 275. When you do this, you will get 294.25 dollars (total price)


To find how much money she has left,

430-294.25=135.75 (money left)

The large cup is best to buy. This is because it costs 11 cents per ounce for the medium cup and 11 cents for the large cup as well. You get almost double the amount for the same price with the large cup.
