The school store sells spiral notebooks in four colors and three different sizes. The table shows the sales by size and color for 400 notebooks. What is the experimental probability that the next customer buys a red notebook with 150 pages? Enter your answer as a simplified fraction. Enter your answer as a simplified fraction.

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

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

answer is because 4×10=40

and 98×4= is 392

40,392
