Ina certain chemicl reaction, the ratio of zinc to copper is 4 to 19. a jar of the chemical contains 950 grams of copper. how many grams of zinc does it contain

The jar has 200 grams of zinc.

Solution:

Given that , In a certain chemical reaction, the ratio of zinc to copper is 4 to 19.  

A jar of the chemical contains 950 grams of copper.  

We have to find how many grams of zinc does it contain  

Now, we know that,  

19 grams of copper ⇒ 4 grams of zinc

Then, 950 grams of copper ⇒ "n" grams of zinc

So, by chris cross method n x 19 = 4 x 950

19n = 4 x 950

19n = 3800

n = 200

Hence, the jar has 200 grams of zinc.

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
