Answer:
(a) Sandra earns $15 per hour
(b) Sandra earns more per hour
Step-by-step explanation:
(a) y=15x tells Sandra's earnings for x hours. To find Sandra's earnings for 1 hour, let x=1.
... y = 15·1 = 15 . . . . Sandra earns $15 in 1 hour.
(b) To find Susan's earnings you can choose any number of hours and divide that into the corrsponding number of dollars. The math is really easy if you choose the last table entry:
... $80/(10 hours) = $8/hour
Sandra's earnings of $15 per hour are more than Susan's earnings of $8 per hour.
_____
Another way to compare the wages is to pick one of the hour numbers from the table and compute Sandra's equivalent earnings. Again, if we choose 10 hours, the math is easy
... y = 15·10 = 150
Sandra earns $150 for 10 hours' work, while Susan only earns $80 for the same time.
