Bianca Holden · Answer 1

You need to use a system of equations with 2 variables

where x = # of paintbrushes bought

and y = # of paint units bought

the first equation would be

.95x+.99y=4.87

Usually there is more information given in these problems so that you can make the second equation. Did the problem say how many total items were bought or anything else because given this information you cannot make a second equation and therefore cannot solve for both variables. Also, the wording is unclear, did she spend 4.87 on just paintbrushes or both brushes and paint.

Vinnie · Answer 2

She bought 2 paintbrushes and 3 paints. because if 5 multiplied by anything the result will only 5 or 0. but to get 7 you need to multiply 9 by 3
