Steven thinks that he will spend about 70 dollars. thus it is not a reasonable amount. hence the actual total cost is $ 48.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables. A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given that steven wants gifts for his 2 little brother and 2 older sisters he plans on spending $12 dollars on each one.
But steven thinks he will spend about 70 dollars.
Which is not a reasonable amount.
It would be 4 x $12 is about 4 x $12 = 48 dollars
Therefore, the actual total cost is $ 48.
Steven thinks that he will spend about 70 dollars. thus it is not a reasonable amount.

From the calculation below, the probability that a tourist will spend more than $250 on the 2 legs of the trip is 2/3.
<h3>How do we calculate the amount spent using probability?</h3>
From the question, the number of possible options available and their total amount is as follows:
Airplane and Van = $350 + $60 = $410
Airplane and Cab = $350 + $40 = $390
Bus and Van = $150 + $60 = $210
Bus and Cab = $150 + $40 = $190
Train and Van = $225 + $60 = $285
Train and Cab = $225 + $40 = $265
From the above, it can be observed that we have a total number of 6 different options available and 4 of the options are more than $250.
Therefore, we have:
Probability of spending more than $250 = Number of options that are more than $250 / Total number of different options = 4/6 = 2/3
