Help pics below for part b the choices are The seventh-grade class earned more money in September or October by $30, $70, or $190

1.25, September, $30

Step-by-step explanation:

Part A: So, we want to find a number that is 120% of 1.5. This accounts for the 20% of the original as well as the final amount of 1.5 (This is confusing, I totally get why you were stuck!)

So, 1.2 x ? = 1.5

? = 1.5/1.2

? = 1.25

Part B: First, we wanna find what 40% of our original prices are.

1.5 x .4 = .6 (October)

1.25 x .4 = .5 (September)

Then, multiply that by the number of flowers sold.

.6 x 700 = 420 (Oct)

.5 x 900 = 450 (Sept)

So, I believe the answer is that they earned $30 more in September :)

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
