Total muffins and doughnuts = 18
Assumed all doughnuts = 18 x $0.4 = $7.20
But she paid $9.15.
$9.15 - $7.20 = $1.95
$1.95 must have been used to pay for the muffin.
Difference in price between muffin and doughnuts:
$0.55 - $0.40 = $0.15
Number of muffins bought = $1.95 ÷ 0.15 = 13
She bough 13 muffins.
Number of doughnut bought = 18 - 13 = 5
She bought 5 doughnuts
Answer: She bought 5 doughnuts and 13 muffins.
Answer: 2√6
x² - y² can be factored as (x+y)(x-y), so we can write x² - y² = (x+y)(x-y). Plugging the values we already know for x² - y² and (x+y), we have 60 = 5√6 (x-y), so (x-y) = 60/(5√6) = 2√6.

Answer:
The answer is 7 1/24
Step-by-step explanation:
27/8 + 11/3
I multipled 27/8 by 3/3 (needed the 8 to become 24)
I multiplied 11/3 by 8/8 (needed the 3 to become 24)
We get:
81/24 + 88/24
Then you add
169/24
Simplify
7 1/24
