Let's say we have an equation like this 7x + 3. Let x = 4. Then we will do the following:
7(4) + 3 - Replace the x with 4
28 + 3
31 - simplify down

Your question isn't complete as you didn't give the sales tax percent. In order to solve the question, let's assume that the sales tax is 6%.
(a) What is the amount of sales tax that Mr. Speer has to pay?
This will be:
= Sales tax percent × Amount charged
= 6% × $300
= 6/100 × $300
= 0.06 × $300
= $18
The sale tax is $18
(b) What is the total amount Mr. Speer has to pay?.
The total amount will be the addition of the amount charged and the sales tax. This will be:
= $300 + $18
= $318
Answer:

Step-by-step explanation:
The solutions of a quadratic equation are :
x = -3/2 and x = 6
or we can write it as :

Multiplying both values,

Hence, the required quadratic equation is
.
As a fraction it’s 9/10 and a decimal is 0.9
