Question

How do you use numerical expressions to solve real-world problems?

Answer 1

you multiply 7 x 3 then navigate to answer x $8.50

Answer 2

There are many ways to do this, if you wanted to write a numerical expression for: Lauren had $7 she babysits for three hours and earned $8.50 per hour, you would write 7+3x8.50=M. It is much shorter and makes much more sense to write this expression than to write a whole story
