Step-by-step explanation:

First, you look at the prices that are $30 or above.

Next, you look at the frequency for the ones that are $30 or above.

The numbers are 3, 2, and 2.

Last, you add the numbers  3 + 2 + 2 = 7

Step-by-step explanation:

30 and above refers to the 30 mark and above.

3 + 2 + 2 = 7

7 dinners were $30 or more.

Hope this helps. Have a nice day.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
