The answer would be 0.13658537...
but when you estimate it the answer would be 0.14
If his water to cement ratio is 20 to 30, this means that if he uses 20 liters of water, he'd use 30 liters of cement.
The total mixture would then be 20+30=50 liters.
and the water would be 20/50=0.4 or 40% of the total mixture.
The circle graph shows the various percentages of a total of 400 students surveyed.
Those that favored visiting Florida were 38% of the total. Therefore, we have
![\begin{gathered} \text{Florida}=\frac{38}{100}\times400 \\ \text{Florida}=38\times4 \\ \text{Florida}=152 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ctext%7BFlorida%7D%3D%5Cfrac%7B38%7D%7B100%7D%5Ctimes400%20%5C%5C%20%5Ctext%7BFlorida%7D%3D38%5Ctimes4%20%5C%5C%20%5Ctext%7BFlorida%7D%3D152%20%5Cend%7Bgathered%7D)
If 152 of the total 400 students favored visiting Florida, that means the others all put together were 248 students. This means there was 96 more surveyed than those who favored visiting Florida.
Those who favored visiting Florida = 152 surveyed
Those who favored visiting others = 248 surveyed
How many more than favor visiting Florida = 248 - 152
If he only ordered 10 pies at $8.50 each, the total would be $85 +$5 delivery. That would make each pie cost $9.00 each. If he bought 12 pies the total cost would be $102. I think the better deal would be to buy 12 at $8.50 each because the cost different for 2 more pies would only be $12. The last 2 pies would only be $6 each above the cost of the 10 with delivery. My only ? is if they want you to set it up as a proportion, or decide which is the most cost efficient.
