Answer:
7 trophies for $49.00
5 trophies for $30.00
-----------------------------------
Explination:
It says that she wants to pay no more than 7 dollars for each trophy she buys, which means 7 and less. So we have to multiply 7 x the number of trophies, And if it gives you the excact number or less its correct.
So we multiply
7 x 7 = 49 (The excact number, correct)
9 x 7 = 63 (The price they are selling it at is higher, incorrect)
12 x 7 = 84 (The price they are selling it at is higher, incorrect)
5 x 7 = 35 (Paying less, Correct)
3 x 7 (The price they are selling it at is higher, incorrect)

Its really easy if you put your mind into it! Goodluck <3
We want to find x in times of y and z, so we want to have only 1 x on the LHS of equation, so
3x-7y=z /+7z (add 7z both sides)
3x=z+7z /:3 (divide 3 both sides)
- its the result.
