Question

Isaiah And Cooper work at a dry cleaner Ironing shirts.isaiah can iron 25 shirts per hour, and Cooper can iron 30 shirts per hour. Cooper worked twice as many hours as Isaiah And they ironed 340 shirts between them. Write a system of equations that could be used to determine the number of hours Isaiah worked and the number of hours cooper worked . Define the variables that you use to write the system

Answer 1

Answer:

Step-by-step explanation:

340/25 = 13.6 = 13 hours and 10 min

30 x 13.6 = 408 hours

25x+30y= 340 and y=2x can be used to determine the number of hours cooper worked and the number of hours isaiah worked. Where x Isaiah 's working hours and y is cooper's working hours.

Step-by-step explanation:

Isaiah ironing rate per hour = 25 shirts

Cooper ironing rate per hour = 30 shirts

Total shirts pressed = 340

Let,

Isaiah´s number of hours = x

Cooper's number of hours = y

According to given statement;

25x+30y=340   Eqn 1

Hudson worked twice many hours as grace.

y = 2x    Eqn 2

Answer 2

Define Variables:

Let x = the number of hours Isaiah worked

Let y = the number of hours Cooper worked

Isaiah can iron 25 shirts each hour, so in x hours he can iron 25x shirts. Cooper can iron 30 shirts each hour, so in y hours he can iron 30y shirts. The total number of shirts ironed 25x+30y equals 340

Since Cooper worked twice as many hours as Isaiah, Cooper worked more hours, so if we multiply 2 by the number of hours Isaiah worked, we will get the number of hours Cooper worked, meaning y equals 2x.

System of Equations:

25x + 30y = 340

y = 2x
