Answer:

Step-by-step explanation:

Complete question

On Thursday, r centimeters of rain fell on Deborah's garden. On Saturday, 15% more rain fell on the garden.

The expression r+0.15r describes the number of centimeters of rain Deborah's garden got on Saturday. We can also use the expression 1.15r to represent the same quantity.

Match each amount in the situation with the expression that represents it.

Since we have given that

Let amount of rainfall on Deborah's garden on Thursday be 'r'.

According to question, 15% more rainfall on the garden on Saturday.

So, Amount of rainfall on Saturday would be

$r+\dfrac{15}{100}r\\\\=r+0.15r\\\\=1.15r$

Hence, Deborah got 1.15r amount of rainfall on Saturday.
