Question

A meuseum had x visitors on friday. On Saturday it had 150 more visitors than it did on friday. The total number of visitors on friday and saturday was twice the number on sunday. Compared to friday how manu more visitors did the meuseum have on sunday?

Answer 1

75 people.

Explanation:

If Friday is x, then Saturday is 150 + x. The number of people on Sunday then is (Friday + Saturday)/2, thus (x + (150 + x))/2. This then simplifies to (x + 150 + x)/2 ---> (2x + 150)/2 ---> 2x/2 + 150/2 ---> x + 75. So, Friday is x and Sunday is x + 75, to find out how many more visitors the museum have on Sunday than Friday, you subtract the two numbers. (x + 75) - x = 75.
