The system of equations that could be used to determine the number of gift wraps and the gift packs is x + y = 21 and 4.5x + 2y = 79.5
What are linear equations?
Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the system of equations?
A system of linear equations is a collection of at least two linear equations.
In this case, the variables of the system of equations are:
- x represents the number of single wraps
- y represents the number of gift packs
From the question, we have:
Total gift = 21
Total minute = 79.5 minutes
Time spent on single wrap = 4.5 minutes
Time spent on gift pack = 2 minutes
So, we have the following system of equations:
x + y = 21
4.5x + 2y = 79.5
Hence, the system of equations that could be used to determine the number of gift wraps and the gift packs is x + y = 21 and 4.5x + 2y = 79.5
