To do these, always convert the percents to decimals, so you can subtract it from 1. Remember, 1 is the whole. When you subtract the part that's taken off, you are left with what you have to pay. If you have 20% off of $100, then you are paying for 80% of $100. **of means to multiply** so you would multiply: 0.8X100, which would be $80.

First, multiply 125x0.8

Multiply that answer by 0.7

You should get B. $70

3) multiple 22.90x0.93

You should get D

Alicia bought 3.8 pounds of cashews for $15.74. About how much was the cost per pound?
garri49 [273]
Hello.

To find this answer, you must divide $15.74 by 3.8 lbs. The full answer is 4.14210526. So it was about $4. 

The answer IS reasonable because $4 x 3.8 = 15.2 
15.2 IS close to $15.74 

Have a great day :)
