Answer:

Penelope worked 5 hours.

Sarah worked 10 hours.

Explanation:

Let's start by setting up some equations to represent the given information:

Let x be the number of hours Penelope worked.

Then Sarah worked 2x hours.

The total number of shirts they ironed is given by:

30(2x) + 35x = 475

Simplifying and solving for x:

60x + 35x = 475

95x = 475

x = 5

So Penelope worked 5 hours.

And Sarah worked 2x = 2(5) = 10 hours.

p = 5

So Penelope worked 5 hours.

And since Sarah worked twice as many hours, she worked:

2p = 2(5) = 10

So Sarah worked 10 hours.
