Last month we had twelve days of either corn or carrots in the cafeteria for lunch. There were six more days of corn than carrots. How many days did we have corn?

9 days

Step-by-step explanation:

Given that:

Days whereby there was either corn or carrot = 12 days

There are 6 more days of corn than carrot.

How many days did we have corn?

Let Number of days we had carrot = x

Hence,

Number of days we had corn = x + 6

Total number of days we had either of the two = 12

Hence,

x + (x + 6) = 12

2x + 6 = 12

2x = 12 - 6

2x = 6

x = 6/2

x = 3

Number of days we had corn = x + 6 ;

Hence,

3 + 6 = 9

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
