Answer:
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.
