The total cost of 20 boards is $166. one size costs $6.50, and the second size costs $9.50. how many boards are purchased at eac
o-na [289]

The number of the board's price of $6.50 will be 12 and the number of the boards for the price of $9.50 will be 8.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division

Given that:-

The total cost of 20 boards is $166. one size costs $6.50, and the second size costs $9.50.

Let the number of the boards for the price of $6.50 is x and for $9.50 is y. So the expression will be given as:-

6.50x + 9.5 y = 166

x + y = 20

Put x = 20 - y

6.50( 20 - y) + 9.5y = 166

130 - 6.50y + 9.50y = 166

3y = 166 -30

3y = 36

y = 12

Now the value of x will be:-

x = 20 - y = 20 - 12 = 8

Therefore the number of the board's price of $6.50 will be 12 and the number of the boards for the price of $9.50 will be 8.

arlik [135]

\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}

Actually Welcome to the Concept of the ratio and percentages.

let's be the total kalguksu soup quantity be x

hence, 60% of x = 24 cups, so we get as

===> 60/100 * x = 24

=> 0.6*x = 24

hence, x ==> 24/0.6

=====> x = 40 cups

hence the answer is 40 cups are in total kalguksu soup.
