The probability of spinning an even number on a spinner is 2/5.

The probability of pulling an even number from a deck of cards is 5/13.

Which is more likely?

• Even number on a spinner because 2/5 > 5/13

• Even number from a deck of cards because 5/13 > 2/5

• They are equally likely because 2/5 = 5/13

• Even number on a spinner because 2/5 < 5/13

Omar uses a laser printer that prints 30 pages per minute. On Monday, he prints 8 pages. On Tuesday, he prints more pages. Omar prints a total of 143 pages on Monday and Tuesday. Let m be the amount of time, in minutes, he spends printing on Tuesday. Part A Create an equation using m to model the amount of time Omar spends printing on Tuesday.

• 30m + 8 = 143

• 30m = 143 + 8

• 30m - 8 = 143

• 8m + 30 = 143
