neonofarm [45]

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
