Will give brainliest. edwin graphs the relationship of the gallons of milk he buys in terms of dollars. sam buys milk from a different shop. he writes an equation for the amount he spends on milk, p = 3.4g, where p is the cost and g is the gallons of milk bought. who buys milk at a lower rate, and what is the price? a) edwin buys milk at a lower rate, $3.40 per gallon. b) edwin buys milk at a lower rate, $3.50 per gallon. c) sam buys milk at a lower rate, $3.50 per gallon. d) sam buys milk at a lower rate, $3.40 per gallon.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
