Pam laid three times as many tiles on Saturday as she laid on Sunday. If Pam laid 80 tiles over the weekend altogether, how many tiles did she lay on Saturday?
x + 3x = 80
4x = 80
x = 20 tiles on Sunday
20 tiles
27 tiles
54 tiles
60 tiles
60
20
To find out how many tiles Pam laid on Saturday, we need to set up equations based on the given information.
Let's assume that Pam laid x tiles on Sunday. According to the problem, she laid three times as many tiles on Saturday, which would be 3x.
We also know that the total number of tiles she laid over the weekend is 80. Thus, the equation can be written as:
x + 3x = 80
Combining like terms, we get:
4x = 80
Now, we can solve the equation by dividing both sides by 4:
x = 80 / 4
x = 20
So, Pam laid 20 tiles on Sunday. To find out how many tiles she laid on Saturday, we can substitute this value back into the equation:
3x = 3 * 20
3x = 60
Therefore, Pam laid 60 tiles on Saturday.
