Answer:
The cost of r rides = 2r + 10
The cost of 15 rides = $40
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
Assume that the cost of r rides is c
∵ The number of the ride is r
∴ x = r
∵ The cost of r rides is c
∴ y = c
∵ The price of admission into the park is $10 ⇒ initial amount
∴ b = 10
∵ She will have to pay $2 for every ride ⇒ rate of change
∴ m = 2
→ Substitute them in the form of the equation above
∴ c = 2r + 10
∴ The cost of r rides = 2r + 10
∵ She goes on 15 rides
∴ r = 15
→ Substitute it in the form of the equation
∵ c = 2(15) + 10
∴ c = 30 + 10
∴ c = 40
∴ The cost of 15 rides = $40
Answer: 28
Step-by-step explanation:
there are 3 boys for every 4 girls, so 4 times 4 is equal to 16. Now just multiply 3 times 4. 16 + 12 = 28.

Step-by-step explanation:
Complete the chart by marking each of the expenses in the correct cell depending on whether the expense occurs montlhy, quarterly, annually, etc. as shown in the chart.
<h3>What is a check-off matrix?</h3>
This is a type of chart that is completed by adding X to the cells. In the case of expenses, check-off matrixes help you to visualize how often every expense occurs, and therefore it can be useful to control or monitor expenses.
This type of matrix often includes:
-Columns with the months of the year or the initals of these. June = J.
-Rows that show the expenses a person has.
<h3>How to do a check-off matrix?</h3>
- List the expenses
- Make an X in each of the cells that the each expense should occur.
- Verify the information once the chart is finished.
