X = bracelets y = necklaces there are 23 of them in total (necklaces + bracelets) x + y = 23 bracelets are $2 each and necklaces are $3 each...totaling $55 2x + 3y = 55
You have to plot the y intercept which is (0,3) and use the slope 1/2

When the dept of the water is 3/5 of the height of the cone, the radius of the water's surface is 3/5 of the radius of the cone: 1.2 ft. The rate of change of depth is equal to the rate of change of volume divided by the area of the surface:
dh/dt = (dV/dt)/A = (dV/dt)/(π·r²)
= (3/2 ft³/s)/(π·(1.2 ft)²)
= 25/(24π) ft/s ≈ 0.3316 ft/s
