Answer:
It's A, c =2.5d
Step-by-step explanation:
When it comes to problems like this, I usually look through the answers and try to plug in the numbers until I get the right equation that fits with the graph.
2.5(5) = 12.5
2.5(10)= 25
2.5(15)= 37.5
2.5(20) = 50
2.5(25) = 62.5
If you compare this to the graph, you'll notice the solutions are the same as the Total Cost (c). That's because c= 2.5d is the right equation for this graph. (Sorry if my explanation is confusing)
691 = A+ S
A=S+59
691 = S+59+S
691=2S+59
691-59 = 2S +59 -59
632 = 2S
316= S
Answer:
Percent 250 of 275 is 90.9%
Step-by-step explanation:
We have to find 250 is what percent of 275.
Let X be the percentage, then
=> X = ![\frac{250}{275} \times 100](https://tex.z-dn.net/?f=%5Cfrac%7B250%7D%7B275%7D%20%5Ctimes%20100)
Now simplyfying the above relation we get
=> X = ![0.909\times 100](https://tex.z-dn.net/?f=%200.909%5Ctimes%20100)
=> => X = 90.9 %
Hence 250 is 90.9% of 275
