Unit 4 Multi-Step Equations

The Hanauma Bay gift shop orders a big box of 250 reusable metal water bottles. The shop pays a wholesale price of $6 for each bottle. During shipping, 14 of the bottles get completely crushed and cannot be sold. The shop sells all of the remaining undamaged bottles for $18 each.

A rental shack down by the beach rents out a snorkel gear set (mask, snorkel, and fins) for $24 a day. On Tuesday, they rent out 85 sets. On Wednesday, a big tour bus arrives, and they rent out 42 more sets than they did on Tuesday.

A group of marine biology students divides a section of the coral reef into 8 equal zones to count invasive algae patches. In each of the first 5 zones, they count exactly 46 patches. In each of the last 3 zones, they count exactly 62 patches.

A group of student volunteers goes snorkeling through Hanauma Bay to count different marine animals along the shallow reef.

Part A: They count 4 separate groups of Green Sea Turtles (Honu) with 6 turtles in each group. They also spot 14 Hawaiian Monk Seals resting on the rocks. What is the total number of turtles and seals the volunteers counted combined?

Next, the students look for the Humuhumunukunukuapuaʻa (the famous reef triggerfish). They spot exactly 3 times as many triggerfish as the combined number of turtles and seals they found in Step A. If these triggerfish are split up evenly among 6 different coral heads, how many triggerfish are swimming around each coral head?
