- The family buys 4 airline tickets online.
- The travel insurance costs $19 per ticket.
- The total cost is $752.
An equation that models this problem could be
Basically, we know that the insurance costs $19 which represents an additional costs after the price per ticket, that's why we need to add them. Then, we know that the familiy bought 4 tickes, that's why we multiply by 4, and finally, the total cost must be equal to 752, according to the problem.
<h3>B.</h3>To find the price of one ticket, we just need to solve the equation for
Therefore, one ticket costs $169.

Answer
given,
apple tree in orchard = 30
yield of apple = 450 apples
yield reduced per tree = 8 apples
number of trees added be x
trees added to maximize the yield = ?
total yield = (30 + x)(400 - 8 x )
T = 12000- 240 x + 400 x - 8 x²
T = - 8 x² + 160 x + 12000
max will occur when
x = 10 (to be added)
maximum yields = - 8 (10²) + 160 x 10 + 12000
= 12800 apple
maximum yield of the orchard is 12800 apple
