Use the table below to answer the questions. i just took a picture of the answer and stuff.

Part A

340

Add up the values in bold that are in the "total" row or "total" column

For the total row: 200+140 = 340

For the total column: 158+182 = 340

Either way, there were 340 items sold. Note how I'm not including the 60 people who didn't buy anything. So that is why the answer isn't 400.

Part B

The answer to this part is 62 which can be found in row 1 (the hotdog row) and column 2 (the water column).

Part C

53.5% (approximate)

We have 182 people who bought pizza out of 340 items sold, so 182/340 = 0.535 approximately which converts to 53.5%

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
