Hello!
x+2y=10
x=10-2y
6y=-3(10-2y)+30
6y=-30+6y+30
0=0
Hope this Helps! :)
31% × y = 89,9
y = 89,9 × 100/31
= 290
Therefore 31% of 290 is 89,9
Answer:
The 4 packages of 15 tops for $18 is a better deal
Step-by-step explanation:
We can see which set of tops have the lowest unit price.
4 packages of 15 tops for $18:
4*15=60
There is a total of 60 tops for $18, which means each top costs 18/60 dollars, or $0.30.
5 packages of 10 tops for $16
5*10=50
There is a total of 50 tops for $16, which means that each top costs 16/50 dollars, or $0.32.
0.32>0.3
The 4 packages of 15 tops for $18 is a better deal :)
Have a great day
