use words, numbers, or pictures to explain why grayson’s thinking is incorrect.

It is incorrect, the right answer is 0.21

Step-by-step explanation:https:

1) If we multiply 1.47 for 100 up and down, we will have the fraction:

100* =

2) Now we can use division of fractions, it is easier when solving a problem like that:

÷ = *

as we know, when dividing fractions you repeat the first and multiply for de inverse of the second

3) * =

4) Simplify. Divide up and down for 7.

=

5) Dividing the fraction you will find 0.21

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
