The amount of money invested at 12% was $4327 while $1442 was invested at 7%.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount invested at 12% and y represent the amount invested at 7%, hence:
x + y = 5679 (1)
Also:
0.12x = 0.07y + 407.5 (2)
From both equations:
x = 4327, y = 1442
The amount of money invested at 12% was $4327 while $1442 was invested at 7%.
