Answer: $450
Step-by-step explanation:
Given that:
Amount borrowed = $450
Amount charged per lawn = $35
Operating cost per lawn = $8
Jimmy's cost (C(x)) :
Amount borrowed + operating cost
If x lawns are mowed :
$450 + $8 per lawn
$450 + $8x
C(x) = 450 + 8x
Intercept (value of y when x = 0
Value of C(x) ; when x = 0
C(x) = 450 + 8(0)
C(x) = 450 + 0
C(x) = 450
Step-by-step explanation:
you're just going to switch x and y and then solve for y
Answer:
No she is not correct because they ARE correct
Step-by-step explanation:
to figure out if it's proportional you do y over x and simplify...
they would all equal 5
