<span>500 x 700 = 350,000 mm^2 Next, you must find the area of the "circles" or "cakes". 3.14r^2 3.14(25^2) 3.14(625) 1962.5 mm^2 Finally, you will have to divide the area of the baking tray by the area of the circle/cake. 350,000/1962.5 178.34 cakes So, your final answer will be.... Approx 178 circles/cakes can fit in the oven. Hope this helps! Cami</span>

Which equation represents the data shown in the table below?

spin [16.1K]

Answer:

B. y = x +3

Step-by-step explanation:

The fastest way to find this answer is to substitute offered values of x and y into the given equations to see if they are true.

<h3>Substitution</h3>

Using the first line in the table, (x, y) = (2, 5), we have ...

A 5 = 2(2) . . . . false

B 5 = 2 +3 . . . . true

C 5 = 3(2) . . . . false

D 5 = 2 +1 . . . . false

By evaluating a linear equation, we can complete the table:

Number of visits | total cost

2 $132

4 $184

5 $210

8 $288

<h3>How to fill the table?</h3>

We know that her membership fee costs $80.00, and it allows her to get her hair done for $26.00 for each visit, so if she does x visits, then the total cost for these x visits (including the membership fee) is:

c(x) = $80.00 + $26.00*x

So we have a linear equation that models the total cost.

Evaluating the equation in the values of the table we will get the other values.

c(2) = $80 + $26*2 = $132

c(4) = $80 + $26*4 = $184

c(5) = $80 + $26*5 = $210

c(8) = $80 + $26*8 = $288

Then the complete table is:

Number of visits | total cost

2 $132

4 $184

5 $210
