The cost of admission per person to a city art museum is $25.50. In order to encourage school and community groups to visit the museum, the museum manager decides to reduce the cost of admission per person for groups consisting of at least 20 people. For groups qualifying for the discount, the manager will reduce the price of admission per person by $0.15 for each person in the group. A group from Marcus Jr. High is visiting the museum and qualifies for the group discount. The school group can only bring one bus, which will only hold up to 55 people. If the museum profits $630.00 from the group, how many people are in the group?

There are 25 people in the group

Step-by-step explanation:

25.50 x 25 = 637.5 (-$7.5 of discount = 25 x 0.15=3.75)

=25 people discount, the discount was applied twice.

The only number showing for 630 is 22.50 x 28

We subtracted $2.75 in error 22.50 x 28 = 630

28/3 = 9 = 9/2 = 4.5  (28-4.5)

25.25 x 25 =$631.25

= 5 people didn't receive 0.25 discount.

OR only 0.25 was applied for 12 people.

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
