On friday ,a museum had 185 visitors. on saturday, there were twice as many visitors as friday. on sunday, 50 fewer people visited than saturday. how many people visited the museum 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. :-)

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
