891 were sold
.55x1800= 990
10% of 990 roses is 99 (99 is left over)
990-99= 891
Answer: The constant of proportionality is 1.5
Step-by-step explanation:
The equation for constant of proportionality is y=KX. the K stands for the constant of proportionality and since the constant proportionality is 1.5 you will take 1.5 * x and for example x is 2 so you do 1.5 * 2 and you get 3 and 3 is your y. If you plug in the equation you're saying 3 equals 1.5 * 2 which is right.
Z=22
180-120=60
2x+16=60
2x=44
Z=22
