Jamar's class painted 50 square feet of a mural using 4 cans of paint.
On the previous screen, you said that Jamar's class could paint 12.5 square feet per can of paint and use 0.08 cans per square foot of the mural.
They want to paint a total of 310 square feet.
How many cans of paint will they need?

Jamar's class painted 50 square feet of a mural using 4 cans of paint. They want to paint a total of 310 square feet.
How many cans of paint will they need?

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
