Answer:
Kim had bought 12 sandwiches.
Step-by-step explanation:
Given:
Amount spend at Midtown Dine = $35
Amount spend on large order of potato salad = $5
Cost of each sandwich = $2.5
We need to find the number of sandwich did Kim bought.
Solution:
Let the number of sandwich Kim bought be 'x'.
Now we know that;
Amount spend at Midtown Dine is equal to sum of Amount spend on large order of potato salad and number of sandwich Kim bought multiplied by Cost of each sandwich.
framing in equation form we get;

Subtracting both side by 5 we get;

Dividing both side by 2.5 we get;

Hence Kim had bought 12 sandwiches.
C = 150000 + 17n
where,
C = Total Cost per year = Fixed Cost + Variable Cost
n = Number of Widgets produced each year
17n = Variable Cost
150000 = Fixed Cost
Answer:
C. 2.0 < t < 2.5
Step-by-step explanation:
time = distance / speed
The circumference of the lake is given by ...
C = πd = 2π miles ≈ 6.28 miles
Then Johanna's time is ...
(6.28 mi)/(3 mi/h) ≈ 2.09 h
This time is in the interval (2, 2.5), so matches choice C.
___
<em>Alternate solution</em>
If we take pi to be 3, then this boils down to ...
2×3/3 = 2 . . . hours
Pi is on the order of 5% more than 3, so her time will be on the order of 5% more than 2 hours, or just above 2, but not as great as 2.5 hours. This sort of estimating can get you to the correct answer without a calculator.
