Php 120.00 is paid for 5 notebooks at Php 24.00 each. Therefore, the cost of purchase varies jointly as the price per notebook and the number of notebook brought.

  • Joint Variation

Find the total cost of 7 notebooks at Php 26.00 each

Let,

c = total cost

b = number of notebook

A = amount of each notebook

k = constant of Variation

Therefore, c = kAb

[tex]c = kAb \\ 120 = k(24)(5) \\ \frac{120}{120} = \frac{120k}{120} \\ 1 = k \\ \\ c = kAb \\ c = Ab \\ \\ c = (26)(7) \\ c = 182[/tex]

The total cost is Php 182.00 when you bought 7 notebooks at Php 26.00
