A teacher purchased 20 calculators and 10 measuring tapes for her class and paid $495. Later, she realized that she didn’t order enough supplies. She placed another order of 8 of the same calculators and 1 more of the same measuring tape and paid $178. 50.

This system represents the constraints in this situation:




`20c+10m=495`




`8c+m=178. 50`
