Answer:
<u>$911.25</u>
Step-by-step explanation:
We know:
1 yd = 3 feet
So, 1 cubic yards should be *THREE* times the power of what the initial scale factor is, 3 cubed. That would make it:
1 yd = 3 feet
1^3 yd = 3^3 feet
1 cu. yd. = 27 cu. ft.
That means, the price of 1 cubic feet of sand is 27 times of the price of 1 cubic yd price
33.75 * 27 = <u>$911.25</u>
Answer:
25
Step-by-step explanation:
3a=30... equation 1
