A family of 5 bought airline tickets. In addition to their ticket, each person had to pay $39 to check their bag. They spent a total of $1640. Find the price of each airline ticket

289

Step-by-step explanation:

5 people pay 39 each for their bag, so, 5*39 is 195

now you have to subtract the cost of the baggage(195) from 1640 to be able to get the total cost of tickets- 1640-195 is 1445

the last thing you do is divide the total cost of tickets by the number of people- 1445/5 is 289

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
