Question

Compared to last month, there was a 65% increase in the number of houses sold this month. There were x. number of houses sold last month. Write two expressions that can be used to determine the number of houses

Answer 1

x+0.65x and x(1 + 0.65)

Explanation:

Given

Original number of houses last month = x

If there are 65% increase in the number of houses, then;

Increment = 65% of x

Increment = 0.65x

The number of houses sold compared to last month = Original number + Increment

The number of houses sold compared to last month = x + 0.65x

This can also be expressed as x (1+ 0.65)

Hence the required expressions are x + 0.65x and x(1 + 0.65)
