Answer:
- equivalent rate: 7.186%
- compounded 16 times
Step-by-step explanation:
The equivalent interest rate is the rate that would have to be applied so it would earn the same amount in 1 year. It is computed from ...
requiv = (1 +r/n)^n -1
requiv = (1 +0.07/4)^4 -1 ≈ 7.186%
__
"Compounded quarterly" means interest is compounded 4 times per year. In 4 years, it will be compounded 4·4 = 16 times.
__
The balance in the account after 4 years is ...
$600·(1 +.07/4)^(4·4) ≈ $791.96

Answer:
Step-by-step explanation:
let price of one pretzel=x
price of one soda=y
3x+4y=11.25 ...(1)
5x+2y=8.25 ...(2)
multiply by 2
10x+4y=16.50 ...(3)
(3)-(1) gives
7x=5.25
x=0.75
from (1)
3(0.75)+4y=11.25
2.25+4y=11.25
4y=11.25-2.25
4y=9
y=9/4=2.25
cost of one pretzel=$0.75
cost of one soda=$2.25
