Explanation:

Khan Academy

Answer 2

$1200

Explanation:

10 x 100 = 1000

$1000 made last month

30 x 10 = 300

$300 made this month (not including the cancellations)

10 x 10 = 100

$100 lost due to cancellations

300 - 100 = 200

$200 this month

Final calculation: This months income + last months income = total income

200 + 1000 = 1200

$1200 made in the combined months
