Answer:
2x + 3y - 7
Step-by-step explanation:
3x − 2y − 7 + 5y − x =
2x - 2y - 7 + 5y =
2x + 3y - 7
25-3=22 dollars left
then divide the amount of money left by the amount of candy bars
22/13= about 0.13 cents
Match up each of the corresponding sides, and simplify the ratio.
That ratio is the scale factor.
