Answer: c = 75t + 5
Step-by-step explanation:
Slope intercept form would take the form of;
y = mx + c
Where y would be the total cost
m would be the variable cost
x would be the varying quantity
c would be the fixed cost
The total rent cost here is denoted c.
m which is the variable cost would be the $75 per hour
x is the varying quantity which in this case is t hours
c is the fixed cost of $5 for the life jacket.
The expression will therefore be;
c = 75t + 5
