Answer:
The number of people who ordered steak dinner is 5
The number of people who ordered chicken dinner is 2
Step-by-step explanation:
Given as :
The total number of people went for the dinner = 7
The total bill price for the dinner = $ 109
The price for the chicken dinner = $ 12
The price for the steak dinner = $ 17
Let The number of people who ordered chicken dinner = c
And The number of people who ordered steak dinner = s
Now, According to question
The total number of people went for the dinner = The number of people who ordered chicken dinner + The number of people who ordered steak dinner
Or, c + s = 7
And The total bill price for the dinner = The price for the chicken dinner × The number of people who ordered chicken dinner + The price for the steak dinner × The number of people who ordered steak dinner
Or, $ 12 × c + $ 17 × s = $ 109
Now, solving the equations
$ 12 × ( c + s ) = $ 12 × 7
Or, $ 12 × c + $ 12 × s = $ 84
Or, ( $ 12 × c + $ 17 × s ) - ( $ 12 × c + $ 12 × s ) = $ 109 - $ 84
Or , ( $ 12 × c - $ 12 × c ) + ( $ 17 × s - $ 12 × s ) = $ 25
Or, ( 0 ) + ( $ 5 s ) = $ 25
∴ s =
I.e s = 5
So, The number of people who ordered steak dinner = s = 5
Put the value og s in Eq A
∵, c + s = 7
or, c = 7 - s
Or, c = 7 - 5
I.e c = 2
So , The number of people who ordered chicken dinner = c = 2
Hence The number of people who ordered steak dinner is 5
And The number of people who ordered chicken dinner is 2 Answer
Answer:
(D) 59 MPH
Step-by-step explanation:
To do this, we simply must look at what the table is giving us. From the top left corner, we can see that they are supplying us with the mileage between each of the cities given. Since we're going from Dallas to Lubbock, find Dallas on the y-axis and go left until you see Lubbock.
The distance between Dallas and Lubbock is <u>351 miles</u>. Now, we have to take our given information, our desired travel time of <u>6 hours</u>, and divide from the miles to get our speed:
Then, we round up to the nearest whole number to get our answer of 59 miles per hour.
