A restaurant manager wants to purchase 200200 sets of dishes. one design costs ​$1010 per​ set, while another costs ​$5555 per s
Sophie [7]
Unless it was a restaurant for the king ..... i am going to assume your 
200200 is 200
$1010 is $10
$5555 is $55
$78507850 is $7850 


Let x be the number of $10 design set
$10 design set = x
$55 design set = 200 - x

10x + 55(200 - x) = 7850
10x + 11000 - 55x = 7850
55x - 10x = 11000 - 7850
45x = 3150
x = 70
200 - 70 = 130

70 of the $10 design and 130 of the $55 design

If you need to put 1 teaspoon in a 10 gallon tank how many teaspoons for a 8 gallon tank
alex41 [277]

Answer:

0.8\ teaspoon

Step-by-step explanation:

Let

x ----> the number of teaspoon

y ---> the number of gallons

we know that

\frac{x}{y} =\frac{1}{10} ---> equation A

For y=8 gal

substitute the value of y in the equation A

so

\frac{x}{8} =\frac{1}{10}

solve for x

x=\frac{1}{10}(8)

x=0.8\ teaspoon
