A museum offers a 2 hour guided group tour. For groups with fewer than 35 people the cost is $12.25 per person; for groups with 35 people or more the cost is $11.50 per person. The 38 people in the 11:00am tour
group each paid $12.25 in advance. What is the total refund that the museum owes the 11:00am group?

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
