The amount engine oil which should be added to a jerry can that contains 4.3 gallons of gas is 0.172 gallons.
Given that arborist is preparing the fuel mix for her chainsaw before climbing a tree to remove a dead limb when two-stroke chainsaw requires a 4% mix of engine oil to gas and the amount of oil should be 4% of the amount of gas.
We want to find the amount of engine oil which should be added to a jerry can that contains 4.3 gallons of gas.
To find the amount of engine oil convert the mixture of engine oil to gas into decimal.
4%=4/100
4%=0.04
Now, we will multiply the above mixture with 4.3 gallons of gas is
4.3×0.04=0.172 gallons
Hence, the amount of engine oil which should be added to a jerry can that contains 4.3 gallons of gas when two-stroke chainsaw requires a 4% mix of engine oil to gas is 0.172 gallons.
