This is a way to work it out
Answer:
A) y = 8.63 x
B) $224.38
Step-by-step explanation:
The the average monthly cost = (147.98+152.17+165.63)/3 = $155.26
So, For 18 employees the average monthly cost = $155.26
Let the equation that can be used to estimate y, the average monthly cost, in dollars, to buy lunch for x employees. ⇒ y = mx
For x = 18 , y = $155.26
So, m = y/x = $155.26/18 ≈ $8.63
∴ y = 8.63 x
To find the total cost for 26 employees.
∴ x = 26
∴ y = 8.63 * 26 = 224.38
The total cost of a monthly lunch for 26 employees = $224.38
Answer:
The approximate number of gallons of water that flow over the waterfall in 1 day is:
Step-by-step explanation:
To obtain the answer to the question, you must multiply the number gallons of water flow over a waterfall each second (6.5 x 10^5 gal/s) by the number of seconds in a day (8.6 x 10^4 s), as I show you below:
- Gallons of water that flow over the waterfall in 1 day = Number of gallons * Number of seconds in a day.
- Gallons of water that flow over the waterfall in 1 day = 6.5 x 10^5 gal/<u>s</u> * 8.6 x 10^4 <u>s</u>
Now, we must cancel the seconds, then:
- <u>Gallons of water that flow over the waterfall in 1 day = 5.59 x 10^10 gallons</u>
How you can see, <em>once you have multiplied these two values, the answer is the same to the option A</em>.
A because u can clearly see how the line is connected and if u count to where the line is u will see that it is A
