Step 1. Extract appropriate data from the graph. April's cost per click. Google charges 18 cents for a Facebook and Yahoo click in February (14 + 6 = 20 cents). Step 2. Divide 20 by 18 to find the ratio. 20 ÷18 = 1.11 Step 3. Present as a ratio of 1:1.11.
Calculate the percentage drop in Facebook click costs between April and May: ((16 - 13) ÷16) x 100 = -18.75%. Calculate the decrease in the cost of a Facebook click over the following two months. 13 times - (100% -18.75%) equals 10.56 cents. 10.56 times - (100% -18.75%) equals 8.58 cents.
Convert 90 pence to cents. 90 x 1.60 is 144 cents. Calculate the number of Google clicks the advertiser received for 144 cents. 144 ÷ 18 = 8 clicks.
15,000 × $78 = $1,170,000
18,000 × (1-0.22) = 14,040 14040 × $82 = $1,151,280
April 18,000 × $76 = $1,368,000 May 13,000 × $89 = $1,157,000 $1,368,000 - $1,157,000 = $211,000 211,000 / 1,368,000 x 100 = 15.42%
(82 + 77 + 82) / 3 = $80.33
(6K + 4K + 4K) / 3 x 100 = 4,667
50k : 5k 50 / 5 = 10 10:1
40,000-25,000 / 25,000 x 100 = 60% increase 1.6 × 40,000 = 64,000
