Answer:
212 tickets were sold
Step-by-step explanation:
a (adult) + s (student) = 326
8a + 5s = 1972
-5(a + s = 326)
-5a-5s=1630
3a/3 = 342/3
a = 114
114 + s = 326
s = 212
The sum of the percentages of milk and dark chocolate needs to equal 100%.
Since dark chocolate is 25%, then milk chocolate must be 75%
Now we can set up a proportion:
75% = 3 lbs
25% = X lbs
Dark chocolate = (3 x 25%) / (75% x X) = 1 lb
Answer:
-3
Step-by-step explanation:
Well to find the common ratio we need to figure out,
what * 2/3 = -2.
To find that we do -2 ÷ 2/3
= -3
To check -2 * -3 should be 6 which it is.
<em>Thus,</em>
<em>the common ratio is -3.</em>
