Banners at the school store were on sale for $3 off the rugular price. louis brought 4 banners on sale and paid a total of $18. write and solve an equation to find the regular price of one banner

$7.50

Step-by-step explanation:

4 x 3.00 = $12.00  3.00 off the regular price makes it 12.00 for all the banners

12.00 + 18.00 = 30.00   you add the sale price with the 12.00 to get the total of each banner before the store gave the sale price.

30.00 divide by 4 = 7.50   to find out what the regular price of the banner you divide by the total of banners you bought to get the price of each banner before the sale.  

well the 1 and -1 are always after the 0 and the 0 is inthe middle. s thats what i would guess. but i dont know what a slope of 2 is sorry

step-by-step explanation:

if x decreases by 4 then y increases by 10
