Lily spent $30 on a t-shirt a sandwich and two books the t-shirt cost $8.95 in the sandwich cost $7.25 the books each cost the same amount how much do each book cost

The cost of each book is $6.90.

Step-by-step explanation:

Given:

Lily spent $30 on a T-shirt a sandwich and two books the T-shirt cost $8.95 in the sandwich cost $7.25 the books each cost the same amount.

Now, to find the cost of each book.

Total amount Lily spent = $30.

Cost of T-shirt = $8.95.

Cost of sandwich = $7.25.

So, we get the amount after deducting the cost of T-shirt and sandwich from total amount spent:

The remaining amount = $13.80.

As, given the books each cost the same amount. And there are 2 books.

Now, to get the cost of each books by dividing the remaining amount by 2:

Therefore, the cost of each book is $6.90.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
