Step-by-step explanation:
8x + 4y <= 136
2x + y <= 34
trying (15, 9) :
2x + 7y <= 70
2×15 + 7×9 <= 70
30 + 63 <= 70
93 <= 70
that does not work. so, (15, 9) is not a valid point of f(x, y) and therefore also no maximum.
trying (0, 10) :
2×0 + 7×10 <= 70
70 <= 70
that is true.
2×0 + 10 <= 34
10 <= 34
also true.
so, (0, 10) is the correct answer option.
424.8 gallons because you have to multiply the number of miles per gallon by the amount of gallons that the tank can hold. 23.6 times 18= 424.8
proportional because 1*5/3*5=5/15

Answer:
it would be $16 off 40 so the pants would be $24
