The total cost of a cake that serves 20 people is $35.
<u>Step-by-step explanation</u>:
- Total cost = y
- Number of additional servings = x
- The number of additional servings = 20 - 12 = 8. (x=8)
<u>The equation can be formed as</u>:
- Total cost = basic cost + (No. of additional serving
cost per additional serving) - y = 25 + x1.25
- Substitute x=8 in the above equation
- y = 25 + 8(1.25)
- y =25+10
- y = 35
Therefore, the total cost of a cake that serves 20 people is $35.
X / 96.6 = (80.5 - 35) / 80.5 ( because the small and large triangles are similar, because of the parallel lines)
x / 96.6 = 45.5 / 80.5
x = 96.6 * 45.5 / 80.5 = 54.6 m (answer)
Answer:
0.25 * 100 = X
Step-by-step explanation:
If there is a winning ticket in 1 out of every 4 boxes of French Fries sold, then that means there is a 25% chance of getting a winning ticket ( 1 / 4 = 0.25 ) . Therefore we can calculate the total amounts of winning coupons per day with the following formula.
0.25 * S = X
Where S is the amount of boxes sold and X is the amount of winning coupons. If the location sells 100 boxes then...
0.25 * 100 = X
25 = X
We can see that the amount of winning coupons in 100 boxes sold will be 25.
