PLS HELP IM IN A TIMED TEST AND I DONT KNOW WHAT TO DO

Long division the problem is 40 ➗ 348 = ?

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?

For the feasibility region shown below find the maximum value of the function p=3x+2y
