Second option. 1.5% of 2,700 is 40.5. Multiply that by 5 and you get 202.5 add that to 2,700 and you get 2,902.5. Round that and you get 2,903. Hence, the second option is correct.

Answer quick pls!
Flauer [41]

Answer:

$290

Step-by-step explanation:

We can use the equation that Skate Land created to find the total cost

C = 7.50p + 65

p = people so if we have 30 people, we have to solve 7.50 x 30

C = 225 + 65

we can now add the flat fee of $65 to get the total cost for the birthday part

C = $290

hope this helps :)

Chris is 11 5/6 years old. Marian is 1 1/3 years younger than Chris and Jane is 1 1/4 years younger than Marian. How old is Jane
jarptica [38.1K]

Answer:

Step-by-step explanation:

chris is 11 5/6 years old

marian is 1 1/3 years younger...

(11 - 1) = 10 : (5/6 - 1/3 = 5/6 - 2/6 = 3/6 = 1/2)...so marian is 10 1/2

jane is 1 1/4 years younger then marian...

10 1/2 - 1 1/4...

(10 - 1) = 9 : (1/2 - 1/4 = 2/4 - 1/4 = 1/4)....so Jane is 9 1/4 years <==
