19 quantities of item A and 6 of item B were sold, respectively
<h3>How to determine the quantity sold</h3><h3>The missing information in the question are</h3>
- The cost of item A is $4 and
- The cost of item B is $2.
Using the information and the given parameters, we have the following system of equations:
A + B = 25
4A + 2B = 88
Multiply the first equation by 2
2A + 2B = 50
Subtract this equation from the second equation to eliminate B
2A = 38
Divide both sides by 2
A = 19
Substitute A = 19 in A + B = 25
19 + B = 25
Subtract 19 from both sides
B = 6
Hence, 19 quantities of item A and 6 of item B were sold, respectively
