A pie chart shows 30% of a company's budget goes to marketing. If the total budget is $500,000, how much is spent on marketing?

Accepted Answer

$150,000

7 appears three times, more than any other value, so the mode is 7.

Question 3

A student scored 78, 85, 90, and 67 on four tests. What score is needed on a fifth test to average 80?

Accepted Answer

80

Answer

Total needed = 80 × 5 = 400; current sum = 78+85+90+67 = 320; needed = 400 − 320 = 80.

Question 4

A line graph shows temperatures: Mon 68°, Tue 72°, Wed 65°, Thu 70°, Fri 75°. What is the range?

Accepted Answer

10°

Answer

Range = maximum − minimum = 75 − 65 = 10°.

Question 5

If a store marks up an item by 40% and the original cost is $30, what is the selling price?

Markup = 40% of $30 = $12; selling price = $30 + $12 = $42.
