Sarah is shopping for groceries at the local supermarket. She paid for her groceries using a $100 bill recently issued by the US
Tatiana [17]
It is not digital because that would something like applepay. It is also nt representative, since that would be something like food stamps. Commodity money is also a bad answer, since it is goods. You answer would be fiat money, which is paper tender issued by the government. Hope this helps.

What is the interest rate if...<br> Principal = $1,250<br> Time = 4 years<br> Interest = $285.
alexandr402 [8]

Answer:

<h3>The answer is 5.7 %</h3>

Step-by-step explanation:

To find the rate given the principal , time and interest , we use the formula

r =  \frac{100I}{pt}  \\

where

p is the principal

t is the time

I is the interest

From the question

Principal = $1,250

Time = 4 years

Interest = $285

We have

r =  \frac{285 \times 100}{4 \times 1250}  =  \frac{28500}{5000}  =  \frac{285}{50}  \\  = 5.7

We have the final answer as

<h3>5.7 %</h3>

Hope this helps you
