Step 1 ：Boubacar and his children went into a grocery store where they sell bananas for $0.40 each and mangos for $1 each. Boubacar has $15 to spend and must buy a minimum of 18 bananas and mangos altogether. If Boubacar decided to buy 12 bananas, we need to determine the maximum number of mangos that he could buy.

Step 2 ：First, we calculate the amount of money Boubacar will spend on bananas. This is done by multiplying the cost of one banana by the number of bananas Boubacar wants to buy. The cost of one banana is $0.40 and Boubacar wants to buy 12 bananas. So, the total cost of bananas is $0.40 * 12 = $4.80.

Step 3 ：Next, we calculate the amount of money Boubacar has left after buying bananas. This is done by subtracting the cost of bananas from the total amount of money Boubacar has. Boubacar has $15 and the cost of bananas is $4.80. So, the money left is $15 - $4.80 = $10.20.

Step 4 ：Finally, we calculate the maximum number of mangos Boubacar can buy. This is done by dividing the money left by the cost of one mango. The cost of one mango is $1 and Boubacar has $10.20 left. So, the maximum number of mangos Boubacar can buy is $10.20 / $1 = 10.

Step 5 ：The maximum number of mangos that Boubacar could buy is \(\boxed{10}\).
