# Thread: Find Money Earned By Magazine

1. ## Find Money Earned By Magazine

A magazine earned $68 million in 1998 from advertising revenue and subscriptions. If the advertising revenue was 6 times the subscription revenue, how much did the magazine earn from advertising? 2. Define some variables. Let a represent the revenue due to advertising. Let s represent the revenue due to subscription. You are told that together, they amount to 68 million. So, a + s = 68 Then, you are told that advertising was 6 times bigger than subscription. a = 6s You get two equations with two unknowns. Solve for a, the earning from magazine. Post what you get! 3. a + s = 68 a = 6s ======== 6s + s = 68 7s = 68 s = 68/7 Then a = 6s. a = 6(68/7) a = 408/7 times 1,000,000 [since we are dealing with millions]. Is this right? I got a =$58,285,714.

Is this right?

4. Right!

In fact, there is one simple shortcut.

The ratio of money spent on ad versus on subscription is 6:1

Total is 7 parts.

Money spent on advertising becomes $\frac67 \times 68000000 = 58,285,714$

5. I like the shortcut in this question. Good work. Thanks! Can you check my reply to the question about percent spent by consumers in England? I came up with an equation and would like to know if it is correct.
