Answer: $100.70
Step-by-step explanation: 6% is equal to 0.06, so you can add multiply the price of the item by 1.06 because that is the base cost plus the tax. Then you get $100.70.
Answer:
$3
Step-by-step explanation:
Since he’s leaving a 20% tip, we need 20% of 15.
To solve, multiply 20/100 (20%) by 15:
20/100*15 = 300/100 = 3
He will leave a $3 tip.
Two solutions were found :<span> t = 8 t = 0</span>
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "t2" was replaced by "t^2".

<span>Step 1 :</span><span>Step 2 :</span>Pulling out like terms :
<span> 2.1 </span> Pull out like factors :
<span> t2 - 8t</span> = t • (t - 8)
<span>Equation at the end of step 2 :</span> t • (t - 8) = 0
<span>Step 3 :</span>Theory - Roots of a product :
<span> 3.1 </span> A product of several terms equals zero.<span>
</span>When a product of two or more terms equals zero, then at least one of the terms must be zero.<span>
</span>We shall now solve each term = 0 separately<span>
</span>In other words, we are going to solve as many equations as there are terms in the product<span>
</span>Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation :
<span> 3.2 </span> Solve : t = 0<span>
</span> Solution is t = 0
Solving a Single Variable Equation :
<span> 3.3 </span> Solve : t-8 = 0<span>
</span>Add 8 to both sides of the equation :<span>
</span> t = 8
Two solutions were found :<span> t = 8<span> t = 0</span></span>

Answer:
Step-by-step explanation:
Given: 
; find x and y.
Let's start with finding x first. Let's distribute the left side of the equation.
Let's move everything we can to the left side of the equation. Some things will cancel out.
Now, let's move the term that includes 
to the left side of the equation. Everything else should be moved to the right.
Let's get rid of the negative sign in front of by dividing both sides by -1.
To get completely isolated, divide both sides by 
.
Simplify.
Let's solve for y. We will start with the distributed and simplified equation to make it easier.
Now, let's move the term that includes 
to the left side of the equation. Everything else should be moved to the right.
Again, let's get rid of the negative sign in front of the by dividing both sides by -1.
To isolate y, divide both sides by z.
Simplify.
