The question is incomplete. Here is the complete question:
Sunny earns \$12$12dollar sign, 12 per hour delivering cakes. She worked for xxx hours this week. Unfortunately, she was charged \$15$15dollar sign, 15 for a late delivery on Tuesday. How much money did Sunny earn this week? Write your answer as an expression.
Answer:
[tex]12x-15[/tex] is the money earned by Sunny this week.
Step-by-step explanation:
Given:
Hourly earning rate of Sunny = $12
Number of hours worked in a week = 'x'
Money charged for late delivery = $15
Now, we have the unit rate of earning by Sunny. Therefore, using unitary method, we can find the total amount of money earned by Sunny this week by working for 'x' hours.
Money earned in 1 hour = $12
∴ Money earned in 'x' hours = [tex]12\times x=12x[/tex]
Now, money charged for late delivery means money deducted from Sunny's total earning. So, 15 dollars were deducted from Sunny's total earning of [tex]12x[/tex] dollars.
Therefore, the amount left with Sunny can be obtained by subtracting the deducted amount from the total amount. Thus,
Money left with Sunny after deduction is given as:
[tex]=\textrm{Total earning}-\textrm{Deducted amount for late delivery}\\=12x-15[/tex]
