Question

The table shows the price of ordering printed photographs of different sizes at an online site. Reyna wants to make a collage with photographs of different sizes. She plans to order the same number of photographs of each size. The equation below represents this situation, where x represents the number of photographs of each size she orders and C represents the total cost of all the photographs.
(0.09)x + (0.79)x + (2.99)x = C

What is the maximum number of photographs she can order in each size for $40?

Answer 1

so given that she plans to order the same number of photographs of each size.
and we know that

Size Unit Price
4 x 6 $0.09
5 x 7 $0.79
8 x 10 $2.99

and this is the equation what used we can calcule the x value for what the total cost not will be greater than $40

(0.09)x + (0.79)x + (2.99)x = C
so

(0.09)x + (0.79)x + (2.99)x > 40

do you can solve this inequality ?

so like a first step factorize out in the left part the x

wait on your collaboration

hope helped understandably easy
