Question

A pencil costs $3.50 and a pen costs $6.70. Jessica bought m pens. She also bought 4 fewer pencils than pens. Write an algebraic expression for the total amount she spent.


The answer supposed to be 6.70m + 3.5 (m-4). I got confused of what to do
well, she bought m pens, and each cost 6.70

So, the total cost for the pens is 6.70m

same for the pencils, but there are m-4 of them.
