Answer 2

Answer:

Peter should join Lab thinkers to receive a better deal.

Science buddies costs 190$ for six months.

Lab thinkers costs 170$ for six months.

Step-by-step explanation:

The equations are...

Science buddies: 10+30x -> 10+30(6)=190

Lab thinkers: 45+25x -> 45+25(6)=170

Peter saves 20$ if he chooses lab thinkers.
