Astore sold 24 sweatshirts. red ones cost $10.95 and blue ones cost $12.50. total of $289.15 worth of sweatshirts were sold. how many of each color were sold?

17 blue and 7 red sweatshirts were sold

Step-by-step explanation:

We set up a simultaneous equation and solve:

Let r represent the number of red sweatshirts and b represent blue ones.

The total sweatshirts is 24. This gives us:

Red ones cost $10.95

and blue ones cost $12.50

and the total is $289.15

This also gives the equation:

From the first equation we have:

We replace b in the second equation to get:

This means that

b=24-7=17

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
