Final answer:
To calculate how much each student invested in each type of bank account, one would normally set up a system of equations representing the investments and solve for the variables. However, the interest rates for the accounts are not given, making it impossible to solve this problem with the provided information.
Step-by-step explanation:
The student asked about how much money was invested in three different types of bank accounts, given the different interest amounts each of three students earned. To solve this problem, we'll need to use a system of linear equations. Let's assume each account has a different interest rate, and each student invested the same overall amount of money across the three accounts. Let x, y, and z represent the amounts put into the three accounts, respectively.
Sabrina earned $187.50, Jordan earned $159.00, and Noah earned $201.00. If we divide each student's total interest earned by the interest rate of their respective accounts, we would have three equations with the amounts x, y, and z as variables. This system of equations can be solved using methods such as substitution, elimination, or matrix operations. However, the question doesn't provide the interest rates, so we cannot solve the problem without this additional information. If the rates were known, the student's interest earnings would be the sum of the interests from each account.
