Final answer:
Markus can buy 10 Monay breads with his $100.00, while his sister can purchase 15 Monay breads with her $150.00. The cost of one Monay is $10.00, and each quantity is obtained by dividing their amounts of money by the price per Monay.
Step-by-step explanation:
To determine how many Monay bread Markus and his sister can buy individually with their respective amounts of money, we simply divide their amounts by the cost of one Monay bread. Markus has $100.00, and each Monay costs $10.00, so:
Markus: $100.00 ÷ $10.00 = 10 Monay
Similarly, Markus' sister has $150.00, and using the same calculation method:
Sister: $150.00 ÷ $10.00 = 15 Monay
Thus, the correct answer to how many Monay bread Markus and his sister can buy individually is:
A) Markus can buy 10 Monay, and his sister can buy 15 Monay.
