Question

Strawberries cost $2 per pound. Kate buys 5 pounds and gets 20% discount on the total cost. How much does Kate pay for the strawberries?

Answer 1

8$

Explanation:

If strawberries cost $2 per pound and she buys 5 pounds we have to multiply the cost of 1 pound by 5.

`2.5= 10`

The discount of 20% is applied to the $ 10, we calculate how much the value of 20% (using a simple rule of three) is and subtract it from $ 10.

`100\longrightarrow 10\\ 20\longrightarrow x\\ x=(20.(10))/(100)= 2`

`(10-2)=8`
