2. The Miller's are sending out invitations, Eric Signed 1/5 of the invitations. Then James signed 1/8 of the remaining invitations, Tammy signed 20% of the invitations James had left
There were 50 invitations in all, how many invitations are left to be signed?

28

Step-by-step explanation:

Start with 50 invites

Eric signs 1/5 of those and 1/5 of 50 is 10 so we subtract 10 from 50 to get 40

James signs 1/8 of the 40 invites left, leaving them with 35 more invites because 1/8 of 40 is 5 so we subtract 5 from 40.

Then Tammy signs 20% of of the remaining 35 which is 7.

Once again we’re subtracting: this time 7 from 35 which leaves us with 28.

Sorry my explanation is all over the place, I hope it makes sense!

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
