At a laundromat there is 1 more dryer than there are washers. Write a rule to find the number of d dryers for every w washers.

i would say 1+w=d

Sarah is right.

Sarah is wrong.The answer is y=x-1.

wouldn't it be w=d-1?

which is right

To find the number of dryers (d) for every washer (w) at the laundromat, you can create a rule based on the information that there is always one more dryer than the number of washers.

The rule can be expressed as:

d = w + 1

Explanation of the rule:
- "d" represents the number of dryers.
- "w" represents the number of washers.
- Since there is always one more dryer than the number of washers, we add 1 to the number of washers to get the number of dryers.

Example:
Let's say there are 3 washers (w = 3). Using the rule, we can find the number of dryers (d):

d = w + 1
d = 3 + 1
d = 4

So, if there are 3 washers, there would be 4 dryers at the laundromat according to the rule.
