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:
40
Step-by-step explanation:
remember PEMDAS
our equation looks like tihs: 
1. parentheses: in the denominator we have a parentese inside of another parenthese, so start with the inside first: (3-5) = -2.
so now our equation looks liek this 
now we have a mini PEMDAS situation within the parentheses: multiplication comes before addition/subtraction, so multiply -2*2 = -4, so now your equation looks like this:
6-4 =2: so now we're done with parentheses part of PEMDAS, the only thing left is dividing 80/2 which equals 40.
