A train travels from New York City to Washington D.C. and then back again. The table below shows the number of Coach tickets sol

alisha [4.7K]

Answer: $74

Step-by-step explanation:

Let C represent the cost of a coach ticket

Let B represent the cost of a business ticket

Washington: 150C + 50B = 18,450

NY City: 170C + 100B = 27,280

Solve the system using the Elimination method:

-2(150C + 50B = 18,450) → -300C - 100B = -36,900

1(170C + 100B = 27,280) → 170C + 100B = 27,280

-130C = - 9,620

÷ -130 ÷ -130

C = 74

sveticcg [70]

Answer:

$2\frac{38}{125}\ teaspoons$

Step-by-step explanation:

we know that

There are about 125,000 Brine shrimp in 1 pound

1 pound contains 96 teaspoons

There are about 125,000 Brine shrimp in 96 teaspoons

Using proportion

Find out how many teaspoons of brine shrimp represent 3000 Brine shrimp

Let

x -----> the number of teaspoons

$\frac{96}{125,000}=\frac{x}{3,000}\\\\x=3,000(96)/125,000\\\\x=\frac{288,000}{125,000}\ teaspoons$

Simplify

$\frac{288}{125}\ teaspoons$

Convert to mixed number

$\frac{288}{125}\ teaspoons=\frac{250}{125}+\frac{38}{125}=2\frac{38}{125}\ teaspoons$
