Friday = 185 visitors. Saturday there twice as many as Friday, so 185 x 2 = 370 on Saturday. On Sunday you have 50 fewer than Saturday, 370 - 50 = 320.
185 = Friday
370 = Saturday
320 = Sunday So then you just add them.
875 people visited the museum during the three days.
Hope this helps you. :-)
This is the equation 185+185(2)+185-50 185+370+185-50 (you multiply 185 times 2 first) 370+370-50 (you add 185 to 185) 740-50 (you add 370 to 370) 740-50=690 There were 690 visitors during these three days.
A total of 875 visitors attended the museum over the three days. This includes 185 visitors on Friday, 370 on Saturday, and 320 on Sunday. The calculations were based on doubling Friday's attendance for Saturday and reducing Saturday's total by 50 for Sunday's count.
