Real-world Math Problem

📌Your mother pays you 12 GHS per hour to babysit your sister on weekends. You offer your brother , Tachema, 10% of your weekend salary to cover Saturday night from 9 p.m. to 3 a.m.

Total hours in the weekend = 48 hrs

Payment for 1 hr = 12 GSH

GSH → Ghanian Shilling

Total hours Tachema cover → 9 a.m to 3 p.m = 6hrs
Total money earned = 12 * 48 = 576 GHS
Tachema's share
= 576 * 10/100
= 57.6 GHS
Money kept = 518.4 GHS

Estimations

Number of videos watched per day

📌 Estimate the number of videos watched on YouTube per day.

5.33B

Have internet access

2.5B

Have youtube accounts

75%

Are active users and watch 3 videos per day

5.6B

Videos are watched on youtube

Youtube users watch 1 billion hours of video daily

Average video length = 10 minutes
10 minutes = 1/6 hours
=1B/(1/6)
6B videos

Google play store revenue per year

📌 How much money does the Play Store make in a year?

Estimate

7 Billion smartphones

  • Out of 7 billion, 70% are android
    = 5.1B Android phone
  • 70% of android users purchase apps
    = 3.5B Android users purchase apps
  • Average app purchased per user in a year
    = 3 apps


  • Total apps purchased in a year
    = 3 * 3.5B
    = 10.5B apps
  • $3 per app
    = $3 * 10.5B
    Estimated revenue in year = 32.2B

Market size for driverless cars

📌 What is the market size for driverless cars by 2028?

Total Cars Driverless Cars
Cars 1.4 Billion 30 Million
Average cost per car $46,000 $70,000
Market $56 Trillion $2.1 Trillion
CARG 32.3% 8.6%
Electric car

Market size
= initial market * (1+CAGR)^n
CARG → Compound Annual Growth Rate
n → Difference in years
Market size in 2028
= 2.1T * (1+0.086)^3
= 2.7 Trillion

Handling new Technology in Projects
