a man pays 60 cents for every 200 m of gas used plus a fixed charged of $13.75. how much does he pay when he uses 55,000 m of gas?

Answer: $178.75

Step-by-step explanation:

Per 200m of gas, we have $0.60, plus a fixed rate of $13.75

Then for 55,000m of gas we have:

(55,000m/200m) * $0.60 = $165

then the amount he pays is the $165 plus the fixed rate:

M = $165 + $13.75 = $178.75
