stiks02 [169]
<span><span>1.       </span>The restaurant is making 22 ¾ cups of chowder. Each cup of chowder holds 7/8 of a cup.
Then the restaurant charges 2.95 dollars per bowl. Let’s find out how much money will the restaurant earned.
Solutions:
=> 22 ¾ = 22.75 cups of chowder
=> 7/8 = 0.88 cup of chowder it can holds.
Let’s solve to get the correct answer:
=> 22.75 / .88 = 25.85 cups in all.
Then, let’s multiply this with the amount
=> 25.85 * 2.95 = 76.26 dollars.
SO the restaurant earned 76.26 dollars for the chowder.</span>

Find the simple interest earned
Kitty [74]

Answer:

SI = $1,200 ; A = $6,200

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

I = 5000 × 0.03 × 8 = 1200

I = $ 1,200.00

The simple interest accumulated

on a principal of $ 5,000.00

at a rate of 3% per year

for 8 years is $ 1,200.00.
