Given:
Given that the chart shows the prices for a round trip airfare.
We need to determine the cost of 5 round trips airfare to Boston and the cost of Jonathan's family to fly to Chicago.
Cost of 5 round trips tickets to Boston:
Given that the cost of 1 round trip airfare ticket to Boston is $178
To determine the cost of 5 round trip tickets to Boston, let us multiply the ticket by 5.
Thus, we have;
Cost of 5 round trip tickets to Boston = $178 × 5 = $890
Thus, the cost of 5 round trip airfare tickets to Boston is $890.
Jonathan's round trip to Chicago:
Given that Jonathan said that he and his family consists of 4 people including him, would cost less than $1500 to fly to Chicago.
We need to determine that whether it costs less than $1500 to fly to Chicago.
The cost of 1 round trip airfare ticket to Chicago is $489
The cost of 4 round trip airfare ticket to Chicago is $489 × 4 = $1956
Thus, it cost $1956 for 4 people to fly to Chicago.
Hence, to fly to Chicago it costs more than $1500 for 4 people.
Therefore, Jonathan was wrong.
