Good morning all ! Can you help me please ? if we order less than 1000 Liters of domestic fuel, we pay 80 cents per Liter; but if we order more than 1000 Liters, the invoiced price is only 0.7o € / Liter (if we order 2000 L -> we pay only 1400 € uros). 1 °) calculate the price of 1 m³ of fuel oil at 80 cents / Liter 2 °) calculate the price of 1400 L of fuel at 0.7o € / L 3 °) calculate the Volume in Liters paid 980 € uros 4 °) calculate the "Balance volume" Ve (greater than m³, and rounded to the liter) for which the invoice will be 800 € uros 5 °) Olivier says that he ordered 1140 L, calculate the amount of his invoice 6 °) Amal preferred to take 1200 Liters in 1 time rather than 2 times 600 L, calculate the savings made 7 °) draw the segment associated with the first rate, then the half-line associated with the rate "0.7o" in the same reference ( take 1 cm for 100 Liters on the x-axis - study up to 2 m³ - and 1 cm for 100 € vertically), use 2 colors! Graphically find the volume Ve (use dotted lines!) 8 °) conclude on the quantity you would order, justify. THANKS to those who will respond! ☺
