Will give brainliest1# janet put $580 into a savings account for one year. the rate of interest on the account was 6½%. how much was the interest for the year in dollars and cents? (round to the nearest cent)2# jeans plus has a sign that says if you buy 3 pairs of jeans, you get $10 off the total regular price. the regular price is $25 per pair. jeans junction is selling jeans at 15% off the regular price. the regular price is also $25 per pair. would you save more money shopping at jeans plus or jeans junction if you buy 3 pairs of jeans?

1. $37.70 of interest

2. Jeans Junction

Step-by-step explanation:

1. For simple interest, we use the equation where

For this problem, we know P=$580, r=6.5%=0.065, t=1 year. We substitute into the formula and simplify to find the total amount A.

Using this total amount we can subtract the original principle to find the amount of interest.

617.7-580=$37.70 of interest

2. Jeans Plus sells jeans for $25 a pair At regular price, if I bought 3 I would spend 3j=s(25)=$75 and then received $10 off. SO I would spend $65 total.

Jeans Junction also sells jeans for $25 and will give me 15% off. This means I would pay 85% or 0.85 of the price (100-15=85). So if I buy 3, I would spend 3j=3(250=75. Then I can multiply 75(0.85)=63.75. This is the better deal because I spend less.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
