Answer:
a
Step-by-step explanation:
15-4 = 11
11 x 2 = 22
22 + 2/3 = 68/3
Amount of money collected in the 2-day fundraiser is represented by the following equations:
- 12x + 4y = 152 .................. (i)
- 32x + 12y = 420 .................. (ii)
where x is the cost of a chicken lunch and y is the cost of a vegetarian lunch
Multiplying (i) with 3 and subtracting it from (ii)
36x + 12y - (32x + 12y) = 456 - 420
⇒ 4x = 36
⇒ x = 9
Put value of x in (i)
⇒ 12 × 9 + 4y = 152
⇒ 108 + 4y = 152
⇒ 4y = 44
⇒ y = 11
Hence, cost of the vegetarian meal is 11.
Based on your answer where ask to determined the number of outcome and decide whether the event is simple or not.
-So in event A is 4000 and a sample space
-So event B is 500 its just a number of outcome
If you subtract the equation 8.0-8.2=-0.2. If you were to do the opposite then you would answer the equation 8.2-8.0=0.2. So therefore you have two options, -0.2 or 0.2. Good luck!
