Answer 2

Calculation of the Number of Bead Packets Purchased by Vika

To determine the number of bead packets purchased by Vika, we can compare the prices paid by Natasha and Vika for the same type of packets.

According to the information provided, Natasha paid 4 rubles and 50 kopeks for 5 packets of beads, while Vika paid 9 rubles for the same number of packets.

To find out how many packets Vika purchased, we can set up a proportion:

Natasha's cost / Natasha's packets = Vika's cost / Vika's packets

Substituting the given values:

4.50 / 5 = 9 / x

To solve for x (the number of packets Vika purchased), we can cross-multiply and solve the equation:

4.50 * x = 5 * 9

4.50x = 45

Dividing both sides of the equation by 4.50:

x = 45 / 4.50

x = 10

Therefore, Vika purchased 10 packets of beads.
