The $120 cost of the field trip was to be shared equally by all those attending. Since 8 less students attended than were expected, the price per person increased by $0.50. How many students went on the field trip?

52

Step-by-step explanation:

Let the number of students be x

Initial share was:

120/x

With the less students the share is:

120 /(x - 8) = 120/x + 0.5

Solve for x:

120 /(x - 8) = 120/x + 0.5120x = 120(x - 8) + 0.5x(x - 8)120x = 120x - 960 + 0.5x² - 4x0.5x² - 4x - 960 = 0x² - 8x - 1920 = 0x² - 8x + 16 = 1936(x - 8)² = 1936x - 8 = √1936x - 8 = 44x = 52

Solution: beginning of the unit = - 2end of the unit = beginning of the unit + 4end of the unit = - 2 + 4end of the unit = 2final answer: therefore, aila was able to reach 2 ( insert name of unit of measurement ) at the end of the unit.hope this ! : )have a lovely day! < 3
