How Much Iron Oar Does John Need?
John needs 500 saw blades
70 saw blades require
40 lengths of steel
and 30 buckets of steel powder
We know that
40 lengths of Steel require
10 buckets of Iron oar
and 30 buckets of coal
30 buckets of Steel powder requires
30 buckets of iron oar
Calculate the following
How much iron oar is needed to make 500 saw blades ?
How much coal is needed to make 500 saw blades ?
What is the formula?
Oar and coal are collected in 20 buckets per trip.
How many trips are needed?

Oars are usually made of WOOD and are used to propel a small boat.

An oar is something else.

John needs no iron "oar." What he needs is iron ore.
1 saw blade = 0.571428571 length of steel and 0.428571429 bucket of steel powder
1 length of steel = 0.25 bucket of iron ore and 0.75 bucket of coal
1 bucket of steel powder = 1 bucket of iron ore
N = number of saw blades = 500 saw blades
LS = lengths of steel = 40N/70 = 285.7142857 lengths of steel
BSP = buckets of steel powder = 30N/70 = 214.2857143 buckets of steel powder
BIO = buckets of iron ore = 10N/40 = 125 buckets of iron ore
BC = buckets of coal = 30N/40 = 375 buckets of coal
N = LS + BSP + BIO + BC
N = 40N/70 + 30N/70 + 10N/40 + 30N/40
Iron ore, 20 buckets per trip = 6.25 trips
Coal, 20 buckets per trip = 18.75 trips

He needs two oars to row his boat. If you can't master the difference between an oAR and oRE then you should stick to something more suited to your lack of abilities.

500 blades x 40 lengths / 70 blades = 286 lengths
500 blades x 30 buckets powder / 70 blades = 214 buckets powder
286 lengths x 10 buckets iron ore /40 lengths = 71.5 buckets iron ore
286 lengths x 30 buckets coal /40 lengths = 214.5 buckets coal
214 buckets powder x 30 buckets iron ore / 30 buckets powder = 214 buckets iron ore
add up, iron oar = 71.5 + 214 = 285.5 buckets iron ore
coal = 214.5 buckets
total 500 buckets
20 per trip means 25 trips
