Answer:

Option B.

Step-by-step explanation:

We need 2\frac{3}{4} wheelbarrows of sand for 8 wheelbarrows of concrete.

That means ratio between sand and concrete is 2\frac{3}{4}:8

Or \frac{11}{4}:8

Now we have to calculate the amount of sand to make 248 cubic feet of concrete.

If the amount of sand required is x cubic feet then the ratio of sand and concrete will be x : 248.

Since both the ratios should be same therefore,

\frac{x}{248}=\frac{\frac{11}{4} }{8}

\frac{x}{248}=\frac{11}{32}

x = \frac{11\times 248}{32}

x = \frac{2728}{32}

x = \frac{341}{4}

  = 85\frac{1}{4} cubic feet

Option B will be the answer.
