Answer :
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.
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.
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. :-)
