3. model with math complete the bar diagrams to show how to represent the hidden questions. then, write and solve equations.
4. model with math how many more times was the song downloaded on days 1 and 2 combined than on days 3 and 4 combined? complete the bar diagram and write and solve an equation to find the difference, d.

Explanation:

Step1: Find total downloads for days 1 and 2

Add the number of downloads on day 1 and day 2. Let the downloads on day 1 be 99273 and on day 2 be 106548. So, $99273 + 106548=205821$.

Step2: Find total downloads for days 3 and 4

Add the number of downloads on day 3 and day 4. Let the downloads on day 3 be 158289 and on day 4 be 270463. So, $158289+ 270463 = 428752$.

Step3: Find the difference

Subtract the total of days 3 - 4 from the total of days 1 - 2. $428752-205821 = 222931$.
