Answer:
There are 9 lilies and 4 tulips.
Explanation:
Step One: Create Let Statements
Let x= the number of lilies
Let 13-x= the number of tulips
Step Two: Create an Equation
14.85=1.25x+.90(13-x)
Distribute 14.85=1.25x+11.7-.90x
Combine like terms 14.85=11.7+0.35x
Subtract 11.7 from both sides 3.15=0.35x
Divide both sides by 0.359=x
There are 9 lilies and 4 tulips.
