Elena bought 8 tokens for $4.40. at this rate:

1 : how many tokens could she buy with $6.05?

2: how much do 19 tokens cost?

(20 points)

She can buy 11 tokens

Step-by-step explanation:

8/4.40=x/6.05  (i set this up as a proportion. tokens/price=tokens/price)

4.40x=48.8  (cross multiplied)

x= 11  (divided both sides by 4.40)

The correct answers are:

1) 11

2) $10,45

Step-by-step explanation:

First we must start by analyzing the information we have.

We know that Elena bought 8 tokens for $ 4.40.

Now they ask us to find out how many tokens she could buy with $ 6.05.

Having 3 of 4 incognitas, the most convenient thing is to do a cross-multiplication:

if 8 tokens 4.40

       x tokens 6.05

x 4.40 = 8. 6.05

x 4.40 = 48.40

x = 48.40: 4.40

x = 11

In this way we solve the first question.

In the case of the second, we will also do the same since we have 3 of 4 incognitas:

if 8 tokens 4.40

      19 tokens x

8.x = 4.40. 19

8x = 83.60

x = 83.60: 8

x = 10.45

In this way we solve the second question.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
