Do not include units ($) in your answer. copied for free from openupresources.org Type your answer below as a number (example: 5, 3.1, 4 1/2, or 3/2): Part B) Explain or show your reasoning. Type your answer below: Part A) Priya, Han, and Elena, are members of the running club at school. Priya was busy studying this week and ran 7 fewer miles than last week. She ran 9 times as far as Elena ran this week. Elena only had time to run 4 miles this week. How many miles did Priya run last week? Do not include units (miles) in your answer. copied for free from openupresources.org Type your answer below as a number (example: 5, 3.1, 4 1/2, or 3/2): Part B) Elena wrote the equation 1/9(x7)=4 to describe the situation. She solved the equation by multiplying each side by 9 and then adding 7 to each side. How does her solution compare to the way you found Priya's miles? Type your answer below: Part C) One day last week, 6 teachers joined 5/7 of the members of the running club in an after-school run. Priya counted a total of 31 people running that day. How many members does the running club have? Do not include units (members) in your answer. Type your answer below as a number (example: 5, 3.1, 4 1/2, or 3/2): Part D) Priya and Han plan a fundraiser for the running club. They begin with a balance of -80 because of expenses. In the first hour of the fundraiser they collect equal donations from 9 parents, which brings their balance to -44. How much did each parent give? Do not include units ($) in your answer.

Type your answer below as a number (example: 5, 3.1, 4 1/2, or 3/2):
Part E)

The running club uses the money they raised to pay for a trip to a canyon. At one point during a run in the canyon, the students are at an elevation of 128 feet. After descending at a rate of 50 feet per minute, they reach an elevation of -472 feet. How long did the descent take?

A musician performed at three local fairs. At the first he doubled his money and spent $30. At the second he tripled his money and spent$54. At the third, he quadrupled his money and spent $72. In the end he had$48 left. How much did he have before performing at the fairs?
