Answer:
P=9h
Step-by-step explanation:
Since Teresa makes 9 dollars for each hour of work, we can say:
9 dollars/1 hour.
Her total pay will be on one side of the equation:
p=
Since we do not know how many hours, we put the variable ‘h’ as it says in the problem in the hour section:
h hours
Every hour, she makes 9 dollars. Every ‘h’ hour, she makes 9xh or 9h dollars since you multiply the amount of money you get each hour by the number of hours. For example, if she worked 2 hours, you multiply 2x9 to get 18 dollars, which is what she earned in 2 hours.
p=9h
B lmk if I’m right have a gud day
I honestly don’t know good luck on your journey hope this helps
If Sky and Max have spent a total of $11,280 only for rental costs for a year, their current monthly rental costs are $815.00. To come up with this figure, you would need to subtract $1500 from $11,280 and then divide that answer by 12 months.
