A florist shop represents its first month’s sales with the equation y = 168 x + 8, where x represents the number of days that th
e shop is open and y represents the sales in dollars. The owner of the shop would like to calculate the number of days it took to reach $3,200 in sales. Which would be used to solve the problem?
$3200 is the total sales in dollars, so we're going to plug that in for y (it says in the equation that y represents the total sales in dollars). And the rest of the equation stays the same.
You take the two sides and make them to the second power so 20 would be 400 and 21 would be 441. You add those numbers to get 841. Than the square root of 841 is the answer which is 29
