Answer:
29) B
30) A
32) A
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 :)
