First 10 days...average daily increase of 0.30 .....total increase for those 10 days is (0.30 x 10) = $ 3
next days.....average daily increase of 0.45....total is (0.45 x 10) = 4.50
last ten days...average daily increase of 0.25.....total is (0.25 x 10) = 2.50
it changed all together : 3 + 4.5 + 2.5 = + 10
It is showing an overall increase, so I guess u should buy it.
Answer:
The number of wreaths Alaina sells is 9 .
Step-by-step explanation:
As given
Alaina is selling wreaths and poinsettias for her chorus fundraiser.
Wreaths cost $27 each poinsettia cost $20 each.
If she sold 15 poinsettias and made $543.
Let us assume that the number of wreaths Alaina sells = x
As the number of poinsettias Alaina sells = 15
Than the equation becomes
27x + 15 × 20 = 543
27x + 300 = 543
27x = 543 - 300
27x = 243

x = 9
Therefore the number of wreaths Alaina sells is 9 .
