Solving Two Equations by Elimination Word Problem

[rickybicky123]

Dear teacher. There is one step I don't understand.

You say the prices are 4$ PER card and 10$ PER box.

I thought whenever you used 'per' ... you had to use a division.

So you say 10c but why not 10/c ?

(for example you also say 30 m/s (metres PER second)

you messed up on the third slide. you said 10c and 4c when it should be 10c and 4w. by the way i am in 7th grade and in algebra
