to solve this, you need to set up an equation to solve for <em>x, </em>the number of square meters waxed in an hour:

you can use cross multiplication to solve for x:


so jessica can wax 100/3 square meters per hour. you can convert this to decimal form (which would be 33.3 repeating) or you can leave it in fraction form.
4n+25=5n+20
20+25=25+20
45=45
