Given the statement:
Kim earns $30 for babysitting on Friday nights she makes an average of $1.25 in tips per hour.
Write the function of Kim’s earning and solve for how much she would make after 3 hours
Solution:
The given can be represented as,
30 + 1.25x
x = number of hours
Hence to find how much Kim is earns, we substitute 3 to the value of x.
= 30 + 1.25x
= 30 + 1.25 (3)
= 30 + 3.75
= $33.75
Final answer:
= $33.75
