Answer: See explanation
Step-by-step explanation:
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:
One clay block = x = $2.50 from before.
One mold = y = $4.00
Step-by-step explanation:
Multiply the second one by -2 to get -12x-2y=-38.00
Add these equations to eliminate y:
-12x-2y=-38.00
3x+2y=15.50
Result: -9x+0y=-22.50
9x=22.50
x=$2.50

Answer:
(a)
(b)
(c)NO
Step-by-step explanation:
GIVEN: Solution A is an
acid solution. Solution B is a
acid solution.
TO FIND: (a) Find the amount of Solution A (in mL) that must be added to
of Solution B in order to produce a
acid solution. (b) Find the amount of Solution A and Solution B (in mL) that can be combined in order to form a
solution that is
acid. (c) Does there exist a combination of Solution A and Solution B that is
acid.
SOLUTION:
(a)
Let total amount of solution A added be 
Total amount of mixture 
As resulting solution is
acid solution.
Amount of acid in final solution is sum of acid in both solutions



(b)
Let amount of Solution A be 
Amount of solution B 
As resulting solution is
acidic solution
Amount of acid in final solution is sum of acid in both solutions




Amount of solution B 
(c)
No as concentration of final solution can not be greater than one with higher concentration.
Hi there! The correct answer is c.
