clay costs $5.60 per kilogram. The art teacher needs to buy 4.5 kilograms for the next project. How much will 4.5 kilograms of c

RoseWind [281]

Well first you have to multiply 4*5.60 to get the 4.0 kilograms

4*5.60=22.4

then divide 5.60/2 to get the .5 kilograms more she needs.

5.60/2=2.8

then just add 2.8+22.4 to get the whole 4.5

2.8+22.4=25.2

it cost $25.20 to get the whole 4.5 kilograms of clay.
