Question

The garden club earned $15 per hour by weeding neighborhood gardens for t hours. A generous donor has agreed to double their earnings. How much did the garden club earn in all? Write your answer as an expression.

Answer 1

We have been given that the garden club earned $15 per hour by weeding neighborhood gardens for t hours.

Let us write an expression for club's earning for weeding neighborhood gardens for t hours.    

$\text{Garden club's earning after weeding gardens for t hours}=15\cdot t$

We are told that a generous donor has agreed to double their earnings. Now let us write an expression for increased earnings of club.

$\text{Club's earning after donor doubled it}=2\cdot(15t)$

$\text{Club's earning after donor doubled it}=30t$

Therefore, expression representing garden club's total earning will be $30t$
