Aaron Miguel purchased a ballpen at a cost of 420 pesos a dozen. at what price will have to sell each ballpen in order to realize a 40% profit on cost?​

step 1

Divide 420 pesos by a dozen

420/12=35 pesos per ballpen

step 2

Increase price of each ballpen by a 40%

Remember that

100%+40%=140%=140/100=1.40

so

1.40*35=49 pesos per ballpen

therefore

the answer is

49 pesos per ballpen
