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

Marcos reads 3, books in 1 3/4 weeks.

Fofino [41]

Answer:

$x = \frac{12}{7}\ books$

Step-by-step explanation:

Given

$3\ books = 1\frac{3}{4}\ weeks$

Required

Number of books in 1 week

Represent the number of books in 1 week with x.

So, we have:

$3\ books = 1\frac{3}{4}\ weeks$

$x = 1\ week$

Cross Multiply

$x * 1\frac{3}{4} = 3 * 1$

$x * 1\frac{3}{4} = 3$

Convert fraction to improper fraction

$x * \frac{7}{4} = 3$

Multiply through by $\frac{4}{7}$

$x * \frac{7}{4}*\frac{4}{7} = 3 * \frac{4}{7}$

$x = 3 * \frac{4}{7}$

$x = \frac{12}{7}\ books$

<em>Hence: 12/7 books were read in a week</em>
