Answer :
Answer:
It is C
Step-by-step explanation:
So 3.75 is the rate of change, when she goes to get a drink it changes it subtracts the amount which Mia has which is $50. so we could put y=-3.75x+50 as the equation because for the number of drink she buys multiply by how much she cost will be the money she has to spend, so by subtracting by 50 her gift card will give how much money she will have in her gift card
Hope this helps
Answer: y= -3.75x + 50
Each drink costs Mia $3.75. Since spending money causes her to lose money, this value will be negative. Therefore, we will put -3.75x in the beginning of the equation.
Mia has $50 on a gift card. Since this amount is positive (she has a positive amount of money) and remains constant (the amount on the gift card won't change) we will put +50 at the end of the equation.
