timurjin [86]

Answer: Equation that represents this situation is 5(x+17) = 1495,

Price of one ticket is 282

Step-by-step explanation:

Here x represents the price of one ticket,

Also, a person bought travel insurance that costs $17 per ticket.

Hence, the total cost of a person = x + 17

⇒ The total cost of 5 person = 5 ( x + 17 )

But, According to the question,

5 ( x + 17 ) = 1495

⇒ x + 17 = 299

⇒ x = 299 - 17

⇒ x = 282

Hence, the price of one ticket = $ 282

Finger [1]

We are required to find the total hours David and Xavier works in a week

The total hours David and Xavier works in a week is 70 hours

let

number of hours Xavier works = 32 hours

number of hours David works = (6 + 32) hours

= 38 hours

Total number of hours David and Xavier works in a week = number of hours Xavier works + number of hours David works

= 32 hours + 38 hours
