Answer:
The total cost is $81.78
Step-by-step explanation:
First lets calculate the tip
tip = cost * percent of tip
tip = 65.42*.25
tip = 16.355
Which rounds to 16.36 since we are working with money and round to the nearest cent
total cost = cost of cut and blowout + tip
= 65.42 +16.36
=81.78

________________________________
Note: In a square, the length of EACH of the four sides of the square is the same.
Area = Length * width.
For a square, length = width.
So for a square, Area = length * width = (length of a side)² = s² ,
Given: A = s² = 144 ft² ;
Solve for the positive value of "s" .
________________________________
→ s² = 144 ft² ; Take the "square root" of each side ;
→ √(s²) = √(144 ft²) ;
→ s = 12 ft.
_______________________________
The answer is: 12 ft.

Answer:
The number of melon was 3 and the number of apples was 45.
Step-by-step explanation:
1. Melons cost $20 per crate and apples cost $8 per create. If the total was 48 crates for $420, you can make the following system of equations, where 
is the number of melons and 
is the number of apples:
2. By applying the Method of substitution, you can solve for in the first equation and substitute it into the second one to find . Then, you can substitute the value of into the first equation to find :
