, 14) Spade Realty sold lots for $23 240 per hectare. What is the total sales value if the lot sizes, in hectares,
were 2 , 3 , 4 ?
Answer: 23240 ∗ ( +3 +4 )
= 23240 ∗ (2 10/20 + 3 5/20 + 4 4/20)
= 23240 ∗ (9 19/20) = 23240 ∗ 9.95
= $231238

versa.
15) Three mechanics worked 15 , 14 , 18 hours respectively. What was the total cost of labour if the
mechanics were paid $14.75 per hour?
Answer: Total Hours
= 15 + 14 + 18
= 15.5 + 14.75 + 18.125
