1. Answer:

   To find out how much Laura earns each week, you can set up an equation using the information given. Let’s call Laura’s weekly pay “W”.

   You know that Laura has saved 5 times her weekly pay, so you can write this as 5W.

   You also know that she spent less than 2 times her weekly pay this week, so you can write this as 2W – X, where X is the amount that she spent less than 2 times her weekly pay.

   Finally, you know that she has 156 left after spending some money, so you can write this as 156.

   You can now set up the equation:

   5W + (2W – X) = 156

   Combining like terms, you get:

   7W – X = 156

   Adding X to both sides, you get:

   7W = 156 + X

   Dividing both sides by 7, you get:

   W = (156 + X) / 7

   Thus, Laura’s weekly pay is equal to (156 + X) / 7. You know that she spent less than 2 times her weekly pay this week, so X must be less than 2W. However, you don’t know the exact value of X, so you can’t find the exact value of Laura’s weekly pay.
