Question

Mr. Hamilton went to Reily's Steakhouse for dinner. The table shows the relationship between the number of steaks and the cost. Number of Steaks (s) 0 1 2 3 Cost in Dollars (c) 0 X $25.98 $38.97 $51.96 Which statement(s) is (are) true? Select ALL that apply. A. At Reily's Steakhouse, 1 steak costs $13.99. B. At Reily's Steakhouse, 5 steaks costs $64.95. C. The equation which represents this relationship is c = 10.99s + 4. D. The equation which represents this relationship is c = 12.99s. E. There is a proportional relationship between the number of steaks and the cost.

Answer 1

We can find the price of one steak using that two steaks cost $25.98, then, the price of one steak is

`(25.98)/(2)=12.99`

12.99 dollars.

Then, the price for 5 steaks is

`5*12.99=64.95`

The equation that represents the relationship can be obtained replacing m=12.99 and b=0 in the slope-intercept form of the line equation

`\begin{gathered} y=mx+b \\ y=12.99x \end{gathered}`

Using this information, we conclude that the statements that are true are

B. At Reily's Steakhouse, 5 steaks costs $64.95

D. The equation which represents this relationship is c = 12.99s.

E. There is a proportional relationship between the number of steaks and the cost.​
