Answer: 72
Plan A = 30 +0.15x
Plan B = 16 +0.20x
30+0.15x = 16+0.20x
subtract 16 from each side
14 +0.15x = 0.20x
subtract 0.15x from each side
14=0.05x
x = 14/0.05 = 280 minutes
280*0.15 = 42 +30 = $72
280 * 0.20 = 56 +16 = 72
280 minutes and cost $72 each
Step-by-step explanation:
Step-by-step explanation:
the line passing through the points (-7, - 7) and (4,-7).
Slope: (-7+7) /(4+7) = 0/11 = 0
this is a horizontal line
through the points (4,7) and (4, -6).
slope: (-6-7) /(4-4) = -13/0 = oo
this is a vertical line

∴ Area of painting = length × breadth
= 40 cm × 35 cm
= 1400 cm²
∴ Its surface cover 1400 cm².
