24 is 2% of 120. It’s not that hard
To determine the total time it needs for the two painters to completely paint the whole wall space, we need to relate the total area of the wall to be painted and the time they need. So, base from the problem, the relation would just be a linear function. We do as follows:
let A = total area of the wall space
t = total time they both need
Painter 1 = <span>190 square feet per hour
Painter 2 = </span><span>130 square feet per hour
total area = 1200 ft^2 (3) = 3600 ft^2
The function would be:
A = 190t + 130t
3600 = 190t + 130t
3600 = 320t
t = 11.25 hrs
</span><span>
</span>
The graph that would best fit an exponential function is the fourth graph.
My answer was deleted but ill post it again. it is a line plotted at the point (-2,-0.5) and the slope is down 1, right twice. this is a negative line.

2 square faces marked with 1,2,3,4,5,6,7,8 or 9 or left blank, dots- important to remember.
This is part of how I do word problems. I cannot help further, I don't get it.
