The science club went on a two-day field trip. the first day the members paid $40 for transportation plus $14 per ticket to the planetarium. the second day they paid $85 for transportation plus $11 per ticket to the geology museum. write an expression to represent the total cost in dollars for two days for the n members of the club.

(40 + 14n) + (85 + 11n) = total

Step-by-step explanation:

Two brackets must be needed as there are two days which both contain different calculations.

The first bracket must contain 40+ because that is the price of transportation and wont change. Then, if there are n members that each cost 14 then we can show this by 14n (14 * n)

40 + 14n

Second bracket must contain +85 because that is a variable that wont change. Then if there are n members that each cost 11 then this can be shown by 11n (11 * n)

85 + 11n

Now, put brackets over both and add them together:

(40 + 14n) + (85 + 11n) = total

Which is the expression!

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
