Complete question :
The garden club earned $15 per hour by weeding neighborhood gardens for tt 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:
($15t × 2)
Explanation:
Given the following :
Amount earned per hour = $15
Number of hours = t
Amount earned for t hours = (amount earned per hour × number of hours)
= (15 × t) = $15t
Doubling this amount means multiply the amount earned by 2
= $15t × 2 = $30t
