Let’s solve this step by step. :)

First, let’s assign variables for the missing number: x and y.

so the 3 numbers would be x, y and 28

then we have 3 scenarios:
28 + x = 61
28 + y = 76
x + y = 81

Using the first equation, we can get x = 61-28 = 33

Using the 2nd equation, we can get y = 76-28 = 48

then, we can verify if our answer is right by substituting these values in the 3rd equation:

x + y = 81
33 + 48 = 81
81 = 81 ✔️

So the 3 numbers are 28, 33 and 48.

Avery received $80 in cash for mowing lawns. She did the following with the $80. Put 20% of the $80 into a bank account. Spent 1

Answer:

$48

Step-by-step explanation:

To start off, we know that Avery put 20% of the $80 in her bank account. We can figure out how much 20% of 80 is by multiplying 80 by 20% and then subtracting that number from 80. Remember to switch 20% to its decimal form (20% -> .2).

Step 1) 80 x .2 = 16

Step 2) 80 - 16 = 64

Next, we have to figure out how much 1/4 of the remaining $64 would be. We just simply divide 64 by 4 to figure out how much Avery spent.

Step 3) 64 / 4 = 16

Lastly, since we know Avery spent 16 dollars, we can subtract the 16 from 64 to get our final answer.

Step 4) 64 - 16 = 48
