Answer:
62 + 64 + 55 + s = 242
61 students will ride Bus #4.
Step-by-step explanation:
The equation I will use here is 62 + 64 + 55 + s = 242
62 + 64 + 55 + s = 242 {Going from left to right, subtract 62, 64, & 55 from 242}
64 + 55 + s = 180 {242 - 62 = 180}
55 + s = 116 {180 - 64 = 116}
s = 61 {116 - 55 = 61}
61 students will ride Bus #4.
