Step-by-step explanation:
I guess, the question is, how many miles were driven ?
if that is the case, then
we need to deduct the basic fee of $14.75, as this would have been paid, even if they did not drive a single mile.
so, 50.45 - 14.75 = $35.70
that is the actual cost for the driven miles.
how many miles ?
well, how often do $0.15 fit into $35.70 ?
35.7 / 0.15 = 238 miles.
this customer had been driving the moving van for 238 miles.
Let's say a = number of ordered soups, b = number of ordered sandwiches.
Then 4.5a + 7.75b = 113.50, and a and b are integers between 0 and 18 inclusive.
How do we tackle this? If all ordered soup, the cost would be $81, so we'll have at least 4 sandwiches. If all ordered sandwich, the cost would be $139.5, so at most 15 sandwiches were ordered. You also know an even number of sandwiches was ordered, to let the price end at 50 cent.
If you brute-force from 4,6,8,10,12 to 14 sandwiches, you find the answer at 10 sandwiches and 8 soups.
10*7.75 + 8*4.50 = 113.50

Answer:
Trigonometry can be used to measure the height of a building or mountains
Step-by-step explanation:
if you know the distance from where you observe the building and the angle of elevation you can easily find the height of the building. Similarly, if you have the value of one side and the angle of depression from the top of the building you can find and another side in the triangle, all you need to know is one side and angle of the triangle.
First use PEMDAS so 26x2=52
52-3=49
4+49=53
53x4
