From 1980 to 2000, the consumer price index (CPI) increased from 82.4 to 172.2. If a pound of margarine cost $0.51 in 1980 and the price of margarine increased at the same rate as the CPI from 1980 to 2000, approximately how much did a pound of margarine cost in 2000?

Answers

Answer 1
Answer:

Answer:

the answer is $1.07


explanation : you divide the price by the cpi (0.51 / 82.4) this gives you 0.00619


so if you want to find the price or the cpi you just need to multiply the number you do have by 0.00619 and this will give you the missing information

Use the following compound interest formula to complete the problem. Sandra has two credit cards, P and Q. Card P has a balance of $726.19 and an interest rate of 10.19%, compounded semiannually. Card Q has a balance of $855.20 and an interest rate of 8.63%, compounded monthly. Assuming that Sandra makes no purchases and no payments with either card, after four years, which card’s balance will have increased by more, and how much greater will that increase be?
a.
Card Q’s balance increased by $7.22 more than Card P’s balance.
b.
Card Q’s balance increased by $6.69 more than Card P’s balance.
c.
Card P’s balance increased by $3.43 more than Card Q’s balance.
d.
Card P’s balance increased by $0.80 more than Card Q’s balance.

Answers

Card P's balance increased by $3.43 more than Card Q's balance. The accumulated total on Card P over the 4 years is $1080.70 and the accumulated total of Card Q is $1,206.28. Based on the principal outlay however, Card P would have netted a higher interest over Card Q when the principal is subtracted from the accumulated value. (For eg. Card P accumulated value $1080.70 less Principal $726.19 equals $354.51).The interests over the 4 years period would be $354.51 and $351.08 respectively, hence Card P having an increase in balance of $3.43 over Card Q.
