You have $6.50 to make copies. It cost $0.45. Write and solve an equality that represents the number of copies

Hoow many exact copies can you make? Let the number of copies be c. We have:
0.45c = 6.50

Type this equation into our search engine and we get:
c = 14.444

We round down and say we can make 14 copies.
c = 14

Now, if the problem asks you for an inequality, we want to see how many copies we can make without exceeding our $6.50 spend. So it's less than or equal to:
c <= 14
