Answer:
39?
Step-by-step explanation:
i subtracted from what she paid for by 5 //her tip was subtracted// then I times that by three for all the friend together, That gave me 39. Do you want me to re-add the tip or was that helpful?
Given function:
y=9.5x+62.1
We have to find the number of minutes x, when y=138.1°F
Put value of y in function.
138.1=9.5x+62.1
Subtract 62.1 from both sides.
76=9.5x
Divide both sides by 9.5.
8=x
or
x=8 minutes
