Can someone please answer this multiple choice question 29 , 30 , 32 please answer it correctly please show work please answer it correctly please please

29)  B

30)  A

32)  A

Step-by-step explanation:

29)  On the graph, it is shown that the line intersects directly with point (2,30)

The 2 represents hours worked, and the 30 represents total money earned

We can set these values equal to find Kelsey's pay per hour

2 hours = $30

Divide both sides of the equation by 2

1 hour = $15

Kelsey's hourly wage is $15 , or B

30)  Costas earns $67.50 per week

0.31 = Food

0.58 = Entertainment

He saves the rest

Find the exact values for food and entertainment

$67.50(0.31) = Food

$67.60(0.58) = Entertainment

$20.93 = Food

$39.21 = Entertainment

$67.50 - Food - Entertainment = Amount of money saved each week

$67.50 - $20.93 - $39.21 = $7.36

Out of the choices, $7.36 is closest to $7, so A is the answer to question #30

32)  13 girls + 12 boys = 25 total students

Janeen is represented as 1 of those students

Janeen out of 25 students = 1/25, or A

Hope this helps :)
