Jason has a collection of 12 model planes.His father added to the collection .The number of planes jason has now can be modeled by equation 12+p=32.The variable p represents the number of new planes.How many new planes did jason father give him?
You can figure this question out by subtracting 32 from 12 (It would look like 32-12 in a calculator) to see how many planes Jason's father added. The answer is either B, C or D. I'll let you figure out which one though.
