Since it is a linear function, the rate on change will be constant. Every time the x value goes down by 1, the y goes down by 3 so when x is 2 y is -4 and when x is 3 y is -7.
So we know that the Bruno's BAkery uses 4/9 barrels and that Cosmo's Bakery uses 6/5 as much. So we have to multiply 4/9 * 6/5 which is equal to 0.53 for one day. Since they are asking for the 3/7 of the week we multiply 3/7 *0.53. This is equal to 0.23 or 23/100 :3
