Pam is making lemonade using a recipe that suggests 2 lemons for every 7 cups of lemonade. How many lemons should she use to make 35 cups of
lemonade?

10 lemons

Step-by-step explanation:

This is easy proportions.

What you do

is that you find the unit rate

or you can do it my way

which is a ton easier

which other people do

so anyways

you know 2 lemons for every 7 cups of lemonade

so you know you want 35 cups of lemonade

so you can multiply 7 by 5 to get 35

so you multiply 5 by 2 lemons to get 10 lemons

2/7 = x/35

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
