i just did my homework with the same question
The answer is x-1 hope that helps not sure if it does
Answer:
145 + 33n
Step-by-step explanation:
Let
n = number of members in the club
Day 1:
Cost = 50 + 18n
Day 2:
Cost = 95 + 15n
Total cost two-day field trip = day 1 + day 2
= (50 + 18n) + (95 + 15n)
= 50 + 18n + 95 + 15n
= 145 + 33n
Total cost two-day field trip = 145 + 33n
An expression that represents the total cost in dollars for two days for the n members of the club is given by 145 + 33n
Collect like terms:
(7x+4x)−2y
Simplify:
11x-2y
I got 9 and 3/8 because you would subtract 18 3/4 from 28 1/8
