Answer:
Let’s say Lila orders x photos. The total cost of the photos would be 0.08x dollars, and with the shipping charge of $4.00, the total cost would be 0.08x + 4 dollars. Since Lila has $20 to spend, we can set up an equation to find out how many photos she can order:
0.08x + 4 = 20
Solving for x, we get:
0.08x = 16 x = 200
So, Lila can order 200 photos for $20.
