Question

Mrs. lin is making several trays of her famous lasagna. She finds the mozzarella cheese on sale for $4.89 per pound at her local grocery store. How much will she pay for four pounds of cheese

Answer 1

We have the following:

since we have the value of per unit (that is, 1 pound) we only have to multiply by the number of pounds like this:

`4.89\cdot4=19.56`

Therefore, she will pay in total $19.56
