How many photocopies can you make for $2.00 at the rate of three copies for ten cents?

Im not 100% that thats correct but im pretty sure it is.

Convert $2 to cents, which is 200 cents.

10 cents = 3 copies

200/10 = 20

20x3 = 60copies

or

10 cents = 3copies,

100 cents = 30copies.

100 x 2 = 200cents.

2x30 copies = 60 copies.

or in ratio form

10cents : 3copies

multiply 20 to get 200, you need to multiply on both sides,

= 200cents : 60copies
