Answer: $10.20
Step-by-step explanation:
Let's first collect the information from the word problem.
<h3><em>We are told:</em></h3>
- Bought 15 pies and 7 cake slices
- Total cost was $55.22.
- Pies cost as much as a slice of cake
<h3><em>We need to solve for:</em></h3>
- Total cost of 1 pie and 2 cake slices
1. Create an equation/expression:
To solve the problem, we need to find the price of a pie and cake slice.
Using the information gathered, the equation is:
<em>x = the cost of the slice of cake.</em>
<em />
2. Simplify/Solve
- Great! we have the price of a slice of cake. ($4.25)
Remember that the pie is of a slice of cake, so now find the price of the pies.
Pie =
Pie = $1.70
- Awesome! We know a slice of cake costs $4.25 and a slice of pie costs $1.70.
3. Check your work!
<em>Check to make sure the math is done correctly!</em>
Good! It is verified that our calculations are correct.
4. Solve!
1 pie and 2 cakes cost:
- $10.20 is our final answer!

Answer:
Step-by-step explanation:
Answer:
112.5 minutes
Step-by-step explanation:
30/2 = 15 miles
45/2 = 22.5 minutes
15 times 5 = 75 miles
22.5 times 5 = 112.5 minutes
Probability works for any given number, so we will assume there are 100 students. Of those 100, 85 of them studied. Since 75% of 85 students passed, we will multiply 85 by 0.75. This gives us 60. So of the students who studied, 60 of them passed. Of the 15 students that didn’t study, 30 percent passed. So we multiply 15 by 0.3. This gives us 4.5 students. Add up 60 and 4.5, and you get 64.5. The probability of passing is 64.5%. If you want to round up, it would be 65%. If you want to round down, it would be 64%. But the most precise answer is 64.5%.
