Question

Can you guys give me a real world problem and answer it for me please. and tell me how you solve it please
I'll mark you as brain list and say thank you and follow you


here is an example

Answer 1

Answer:

A piggy bank contains 7 quarters, 10 half dollars, and 9 dimes. What is the total amount of money in the piggy bank?

Step-by-step explanation:

Step 1 = 7 quarter + 10 half dollars + 9 dimes

Step 2 = (7 * 0.25) + (10 * 0.50) + (1 * 0.10)

Step 3= 1.75 + 5.00 + 0.10

Total = $ 6.85

I hope this helps and have a great day

Also I need help getting a new ranking so if you could give me brainliest that would be amazing. I can help you out with whatever you need help on.

Answer 2

Answer:

In a library, they are charging an initial fee of $5 and an additional fee of $2 for each day. Identify the slope and y-intercept and create a linear equation in slope-intercept form. Find out the total cost for keeping a book for 7 days.

Part 1:   5 is the y-intercept an 2 is the slope

Part 2: y = 2x + 5

Part 3: $19

Step-by-step explanation:

Part 1:

If we graph the situation with the number of days along x-axis and the cost along y-axis, then 5 is the y - intercept when x = 0 representing the initial amount and 2 is the slope since it determines the slope of the line. It is the ratio between the change in y value and the change in x value.

Part 2:

The linear equation with slope m and y-intercept c is:

y = mx + c

Therefore, the required equation is:

y = 2x + 5

Part 3:

For 7 days, put x = 7 in the above equation.

y = 2(7) + 5

= 14 + 5

= 19

Hence, the total cost for keeping the book 7 days is $19.
