A man earned x pesos in 10 days and spent y pesos during each of those days. Write an expression to determine how many pesos he
Vsevolod [243]

Answer:  \dfrac{x}{10}-y

Step-by-step explanation:

Given : A man earned x pesos in 10 days and spent y pesos during each of those days.

i.e. Total earning in 10 days = x

Earning per day =\dfrac{x}{10}    [By unitary method]    (1)

Money spent per day =y      (2)

We know that

\text{Savings = Money earned - Money spent}

i.e. Subtract (2) from (1), we get

\text{Savings = }\dfrac{x}{10}-y

Hence, the expression to determine how many pesos he saved per day will be:-

\dfrac{x}{10}-y
