Answer:
25 cans
Step-by-step explanation:
Given:
Firstly, We need to get how many cans per square foot Jamar will need by calculating;
[tex] \sf \frac{\text{cans}}{\text{ft}^2} = \frac{4}{50} = 0.08/ft^2[/tex]
Now we've gotten the value paint per square foot of the can, we just then need to multiply it by the total paint which is 310 ft^2
[tex] \sf \rightarrow 310 \: \cancel{{ft}^{2}} \times \frac{0.08 \: cans}{ \cancel{ {ft}^{2}} } [/tex]
[tex] \sf \rightarrow 24.8 \text{ \sf cans} \approx 25 \text{ \sf cans}[/tex]
Therefore, since cans are not sold in fractions it would be 25 cans needed but accurately it's 24.8 cans required
