bulgar [2K]
<h3>The number of beads lina has is 31</h3><h3>Laura made a mistake by adding the constant 7 and variable 4b</h3>

<em><u>Solution:</u></em>

Given that,

Laura wrote and solved the following expression to find the total number of beads Lina has

There are 6 beads in each packet

7+4b = 11b

= 11(6)

=66

From given,

Lina has a total of 7 + 4b beads

Given that, There are 6 beads in each packet

Substitute b = 6

7 + 4(6)

Simplify

7 + 24

Add

31

Thus, she has a total of 31 beads and not 66 beads

galben [10]

You are multiplying by 3 each time. This sequence is geometric.

9 = 3*3 = 3^2

27 = 3*9 = 3*3*3 = 3^3

81 = 3*27 = 3*3*3*3 = 3^4

and so on.

The general rule is 3^x which is choice D
