Elvis and Ralph are to make square shapes with matchsticks from a box containing 50 matchsticks. Elvis makes 4-matchstick squares and Ralph makes 8-matchstick squares. If Elvis makes 5 squares and Ralph makes 3, how many matchsticks will be left in the box?
Elvis makes 5 squares with 4 matchsticks each for a total of 5*4 = <<5*4=20>>20 matchsticks
Ralph makes 3 squares with 8 matchsticks each for a total of 8*3 = <<3*8=24>>24 matchsticks
They used a total of 20+24 = <<20+24=44>>44 matchsticks
There will be 50-44 = <<50-44=6>>6 matchsticks left in the box
