Answer:
3:a 4:b
Step-by-step explanation:
if 5^2 x 5^4 you add the exponents so then it would be 5^6
$1.08
you would multiply your cost (1.00) by 8% which is equivalent to .08 and then add to to the original cost. or to skip the middle step just multiply it by 1.08 since you are adding the 8% to 100% of the original cost
Answer:
a. 24.5 $
b. 10.5 $
c. 7/10
Step-by-step explanation:
Given the original price of the sweater is: $ 35.
a) If you pay only 
of the price, then the actual amount paid is: 
= 24.5 $.
b) Total amount Saved = Actual price - Price you paid
Total Amount Saved = 
= 10.5 $.
c) Fraction of the original price saved = Total amount Spent/Actual Price
Total amount Saved = 
=
We can use one formula that has to do with the simple interest add on loan which is: S.I = P * R/100 *T. The simbol S.I is Simple Interest, P is he amount that costs the TV, R is the rate percentage of interest and T is the time of the payment. So the operation will go S.I= 1299*19.25/100*3 and the result is 750.125. This will be the Simple interest and now we are adding the real cost of the TV: 750.125 + 1299 = 2049.17. As the year has 12 months and we are talking about 3 years then 12 months * 3 years will be =36. Then we take the total money and we divide it into 36 and it equals 56.92 which is what they need to pay per month. and now if they pay 800 what will remain will be 1299-800=499 so we do the operation again S.I=p*r/100*T but with the new p=499. So 499*19.25/100*3=288.17 and then 288.17+499=21.8659 =$21.87 and that will be the second answer
