I think you have to count 85 and go down like 85 86 87so the answer is 15
Answer:
f(x) = 4x − 12
Step-by-step explanation:
It's not quadratic. It's linear. Each time x increases by 1, f(x) increases by 4. So the slope is 4. The y-intercept (when x=0) is -12. The equation of the line is therefore:
f(x) = 4x − 12
This is an linear equation, so
y=mx + b
m= money w=weeks
m= -20w +200
14÷0.50
=<u>28</u>
Hope this helped you- have a good day bro cya)
