Answer:
₦40.30
Step-by-step explanation:
Step 1: Find how much each person gets equally
Divide 142 by 3
[tex]142 \div 3\\\\= 47.3[/tex]
Each person's share is ₦47.3
Step 2: Find out how much Ore, Tobi, and Mary has
Subtract 11 from Ore's share
[tex]47.3 - 11\\\\= 36.3[/tex]
Add that 11 to Mary's share
[tex]11 + 47.3\\\\= 58.3[/tex]
Subtract 7 from Tobi's share
[tex]47.3 - 7\\\\= 40.3[/tex]
Add that 7 to Ore's now-share
[tex]36.3 +7\\\\=43.3[/tex]
Tobi's share is 40 naira and 30 kobo
