! !

Solution: 𝑏

# of tickets to bungee jump: 2𝑏 + 5

⎛ 1 ⎞ 3b + 4 ⎜ b ⎟ + (2b + 5) = 33 ⎝ 2 ⎠

Directions: Write an expression for each unknown quantity and write an equation for each word problem. Solve your equation and write your answer in a complete sentence. 7. The number of boys in the Sports Club is four fifths the number of girls. If there are 360 boys and girls altogether in the club, how many girls are there in the club? 8. Michaela’s age is ten years greater than half Jake’s age. If the sum of their ages is 55, how old is Michaela? 9. A certain molecule contains twice as many atoms of hydrogen as oxygen and one more atom of carbon than hydrogen. If there are 21 atoms altogether in the molecule, how many atoms of carbon are there? 10. One number is 35 greater than a second number. If the lesser number is subtracted from twice the greater number, the difference is 87. Find the numbers. 11. The length of a certain rectangle is 3 cm less than twice its width. If each dimension were reduced by 5 cm, the resulting figure would have a perimeter of 16 cm. What are the dimensions of the original rectangle?
