Mason is going to have a lemonade stand. his aunt buys him 10 lbs. of lemons. if he sells each cup for a quarter, how many cups does he need to sell to pay her back?
the price of 1 lb. of lemons is $0.89.
i have already did 0.89 x 10 which gives me 8.90.

8.90 divided by 0.25= 35.6 (round up to 36 because you cant sell .6 cups of lemonade)

he would have to sell 36 cups of lemonade to pay his aunt back

after he sells 36 cups and pays his aunt back the $8.90 he will have $0.10 left to keep for himself

i used to know but i learned it a long time ago sorry

step-by-step explanation:

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
