The one with (1, 10) and (1, 15) because in a function the same x value cannot equal different y values
Answer:
He rides 9 miles a day
Step-by-step explanation:
72(miles) divided by 8(days) would equal 9 miles per day.
There are no expressions to choose from, but it should look something like:
y= total cost= $74.50
x= number ordered= 10
c= cost per lunch= 74.50/10= $7.45
The more lunches that are ordered, the higher the total will go. y depends on what x is.
y= $7.45x
OR
$74.50= 10c
CHECK:
$74.50= $7.45 per lunch * 10 lunches
$74.50= $74.50
ANSWER: y= $7.45x OR $74.50= 10c
Hope this helps! :)
