Valerie purchased x tubes of lipstick at $4 each and y bottles of nail polish at $2 each. she spents less than $12 not including tax. which point represents a reasonable number of lipsticks and bottles of nail polish that valerie purchased?
a) 2,3
b) 1,5
c) 1,3
d) 2,2

This can be solved with an equation.

 

now, as far as I can tell this question was made multiple choice for a reason; just start to plug in numbers. So using the answers x is either equal to 1 or 2. lets try and solve the equation plugging 2 in. When you solve for this you end up with  none of your answers have one where y<2 so x must be 1. so lets solve for x=1.
you end up getting 

The only answer where x=1 and y<4 is C sos c is your answer. Hope this helped! :)
