If George's driveway is a rectangle 12.2 m by 3.0 m, its dimensions in cm are
... 1220 cm long × 300 cm wide × 2 cm deep
Thus the volume of gravel required is
... (1220 × 300 × 2) cm³ = 732,000 cm³
George needs about 0.732 bags, so he will probably need to buy 1 bag.
x - Alma's given number
15•x - the number multiplied by 15 (the correct answer)
5•x - the number multiplied by Alma (Alma's answer)
her answer is 150 less than the correct answer:
5•x = 15•x - 150
15x - 150 = 5x
15x - 5x = 150
10x = 150
<u>x = 15</u>
