Answer:
31.1% increase
Step-by-step explanation:
% increase= 100 X (final-initial)/initial
Answer:
51 hours
Step-by-step explanation:
$15 x 40 = $600
$15 x 1.50 = $22.5
$22.5 x 11 = $247.5
$600 + $247.5 = $847.5
40 + 11 = 51 hours
The number is 5/2 or 2.5
7 is added to six times a number, the result is 22
The number sentence is interpreted this way:
7+6n=22
6n=22–7
6n=15
The goal here is to find out the value of n.
Let’s divide both sides of the equation with 6
6n/6=15/6
n= 5/2 or 2.5
Let’s check by substituting the value of n to the given equation.
Always remember to follow the PEMDAS rule. We will deal with Multiplication and Addition after.
If n=2.5
7+6n=22
7+6(2.5)=22
7+15=22
22=22
Given the result, this means that the value of the number represented by n is 2.5 or 5/2.
