Answer:
$7.50
Step-by-step explanation:
His normal pay is $15/h
Find the OT pay:
OT pay is 150% of his normal pay. Convert 150% to a decimal by dividing by 100 to find the rate in decimal form.
150%/100 = 1.5
Multiply his normal pay by the rate in decimal form.
$15 X 1.5 = $22.5
His OT pay is $22.5/h.
Additional money
= (OT pay) - (Normal pay)
= $22.5 - $15
= $7.5
We always use two decimal places for money.
$7.5 = $7.50
For every hour he works over 40 hours, he is paid an additional $7.50.

Step-by-step explanation:
Just by looking at the graph vertically and horisontally, you can tell what the range and domain is, depending on whether the segments are <em>closed</em> or <em>opened</em>.
* This is a function because it passes the <em>vertical</em><em> </em><em>line test</em>.
** This is kind of like a sine wave.

In this question, we're trying to find cost of one sandwich.
To find this, we must make a systems of equation from the given information:
We would represent sandwiches as "s" and drinks as "d".
Systems of equations:
6s + 4d = 53
4s + 6d = 47
Solve for s:
6(6s + 4d = 53)
-4(4s + 6d = 47)
36s + 24d = 318
-16s - 24d = -188
--------------------------
20s = 130
Divide both sides by s
s = 6.50
This means that one sandwich costs $6.50
Answer:
$6.50
