Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Pedro is an airline attendant. Last week, he worked on flights on 4 small jets and 3 large jets, which could seat a total of 418 passengers. The week before, he was assigned to flights on 5 small jets and 3 large jets, which could seat a total of 464 passengers. How many seats were on each type of flight?

The flights on small jets each had seats, and the flights on large jets each had
seats.

Seats on small jet = x = 46 seats

Seats on large jet = y = 78 seats

Step-by-step explanation:

Let

Seats on small jet = x

Seats on large jet = y

4x + 3y = 418 (1)

5x + 3y = 464 (2)

Subtract (1) from (2)

5x - 4x = 464 - 418

x = 46 seats

Substitute x = 46 into (1)

4x + 3y = 418

4(46) + 3y = 418

184 + 3y = 418

3y = 418 - 184

3y = 234

y = 234/3

y = 78 seats

Seats on small jet = x = 46 seats

Seats on large jet = y = 78 seats

The flights on small jets each had 46 seats, and the flights on large jets each had

78 seats.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

the answer is b
