Answer 3

Calculation of Total Cost

To calculate the total amount spent by both Katya and Lena, we can first find the total amount spent by Katya and then add the total amount spent by Lena.

Katya bought 5 notebooks at 4 rubles each, so the total amount she spent is 5 * 4 = 20 rubles.

Lena bought 4 notebooks at the same price of 4 rubles each, so the total amount she spent is 4 * 4 = 16 rubles.

Therefore, the total amount spent by both Katya and Lena is 20 + 16 = 36 rubles.

So, both Katya and Lena spent a total of 36 rubles.
