Answer 1

Answer:

1. $37.70 of interest

2. Jeans Junction

Step-by-step explanation:

1. For simple interest, we use the equation $A=P(1+rt)$ where

• P is the principle or starting value
• A is the total amount after interest and a period of time
• r is the rate at which interest gathers as a decimal
• t the time in years.

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.

$A=P(1+rt)\\A=580(1+0.065(1))\\A=580(1+0.065)\\A=580(1.065)\\A=617.70$

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.
