Answer:
You would save 92$
Step-by-step explanation:
Discount = Original Price x Discount 40/100
Discount = 230 × 40/100
Discount = 230 x 0.4
You save = $92.00
Final Price = Original Price - Discount
Final Price = 230 - 92
Final Price = $138.00
Hope this helps

Answer:
   There are 232 students at the school.
Step-by-step explanation:
Let s represent the number of students at the school. We are told ...
   174 = 75% × s
   174/0.75 = s = 232 . . . . . divide by the coefficient of s
There are 232 students at the school.
 
        
             
        
        
        
Answer:
- 273 mL of 5%
- 117 mL of 15%
Step-by-step explanation:
Let q represent the quantity of 15% dressing used. Then the amount of 5% dressing is (390 -q). The amount of vinegar in the mix is ...
   0.15q + 0.05(390 -q) = 0.08(390)
   0.10q = 31.2 -19.5 = 11.7 . . . . . . subtract 0.05(390) and simplify
   q = 117 . . . . . . . . . . . . . . . . . . multiply by 10
   390-q = 273
The chef should use 273 mL of the first brand (5% vinegar) and 117 mL of the second brand (15% vinegar).

<em>Additional comment</em>
You may have noticed that the value of q is (0.08 -0.05)/(0.10 -0.05)×390. The fraction of the mix that is the highest contributor is the ratio of the difference between the mix value and least contributor, divided by the difference between the contributors: (8-5)/(15-5) = 3/10, the fraction that is 15% vinegar. This is the generic solution to mixture problems.
 
        
             
        
        
        
Answer:
The equations 9x+8y=14100 and x = y+150 are in the simplest form.
Step-by-step explanation:
Given that:
Russian blue kitten costs $150 more than Manx kitten.
Cost of 9 blue kittens and  8 Manx kittens = $14100
Let,
x be the price of one Russian blue kitten.
y be the price of one Manx kitten.
According to given statement;
9x+8y=14100
x = y+150
Hence,
The equations 9x+8y=14100 and x = y+150 are in the simplest form.
