Question

Please help!! I'll give you a medal 0:-)

Answer 1

Ah been on dis here site for 2 years and never heard about no medals.

total is 460 at most
x+y≤460

y is at least 4 times of x
y≥4x

ok, so realisitcally, yu can't donate negative amounts
only use first quadrant (use only positive x and y axises)
graph the line y=4x
shade to the right of the line
now graph the line y=-x+460 (yint at y=460)
y≤-x+460, so shade below that

see attached graphh
where the 2 graphs intersect is where the solution is (remember use positive x and y axises)
see other garph for graphed thing


so the equations to graph are
x+y≤460 and
y≥4x
