To solve this problem, we need to determine the value of x, which represents the number of acorns Shawna has.
Let's break down the information given:
Number of acorns Shawna has: x
Number of acorns Sheila has: 5x
Number of acorns Danny has: 5x + 3
Total number of acorns: 80
We can set up the equation as follows:
Number of acorns Shawna has + Number of acorns Sheila has + Number of acorns Danny has = Total number of acorns
x + 5x + (5x + 3) = 80
Let's simplify and solve for x:
x + 5x + 5x + 3 = 80
11x + 3 = 80
To isolate x, we subtract 3 from both sides of the equation:
11x + 3 - 3 = 80 - 3
11x = 77
To solve for x, we divide both sides of the equation by 11:
x = 77 / 11
x = 7
The value of x is 7.
#### 7
The answer is: 7
