Nicole owns a small textile company that produces shirts. on a particular day, nicole has one worker come into the shop to make shirts. she must pay the worker $29 per hour and also pay $2.50 per shirt for material costs. the worker created an average of 5 shirts per hour and nicole's total expenses for labor and materials were $290.50. write a system of equations that could be used to determine the number of hours the worker worked and the number of shirts the worker made. define the variables that you use to write the system.

Step-by-step explanation:

Let x be the number of working hours

She must pay the worker $29 per hour

So, Cost of labor for x hours = 29 x

The worker created an average of 5 shirts per hour

So, no. of shirts produced in x hours = 5x

Cost of 1 shirt = 2.50

Cost of 5x shirts = 2.50(5x)

Total expenses for labor and materials =

We are given that  Nicole's total expenses for labor and materials were $290.50

So,  

Hence a system of equations that could be used to determine the number of hours the worker worked and the number of shirts the worker made is

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
