Answer:
feel like its C
Step-by-step explanation:
DJ + decorations = 200+100 = 300
tickets are $5 each
so 5n would be the total amount of money made then you need to subtract 300 ( cost of DJ and decorations )
so answer is: 5n - 300 = 1500
if you want to solve:
5n -300 = 1533
add 300 to each side
5n = 1800
divide both sides by 5
1800/5 = 360 tickets need to be sold
The answer to these 2 questions would be:
1.
.8 is greater than .7.
or.
.7 is less than .8.
Why?
.8 is .1 higher than .7.
.7 + .1 = .8, so the greater than would be placed facing the .8.
2.
.8 is less than 7.
or.
7. is greater than .8.
Why?
You see where the decimal is placed at? It is placed after the 7 which makes the 7. a whole number. While .8 is still a decimal, 7. is way higher than .8 because of where the decimal is at.
This is how we get both our answers, 1. .8 and 2. 7.
Hope this helps!~
A=P(1/2)^(t/h)
P=initial amount
t=time
h=half life
A=final amount
so
A=0.242188 grams
