Sagot :
The cost of 5 tickets at the same rate is $35
From the question, we have that Mohammed bought 3 tickets for $21. This can be written as:
- 3 tickets = $21
To get the cost of 5 tickets at the same rate, we can write:
- 5 tickets = x
Divide both equations to have:
[tex]\frac{3}{5} = \frac{21}{x}[/tex]
Cross multiply
[tex]3x = 5 \times 21\\3x = 105\\x = \frac{105}{3}\\x=35[/tex]
Hence the cost of 5 tickets at the same rate is $35
