Answer:

1.0*10^(-1) (but 0.10 would also be appropriate)

Step-by-step explanation:

Rewrite 35.83 x 0.0028 as 3.583*10^1 and 0.0028 as 2.8*10^(-3).

Estimate the product: 36 times 3 is 108.

Multiply 3.583 and 2.8 together, obtaining 10.0324.

Noting that 10^1 * 10^(-3) = 10^(-2), write the intermediate answer as:

10.0234*10^(-2).

Move the decimal point one place to the left, and then, in compensation, rewrite this expression as 1.0234*10^(-1).

Finally, rewrite this result as 1.0*10^(-1). Since 0.0028 has just 2 signficant figures, 1.0 (2 significant figures) is appropriate. That's 1.0*10^(-1).

The students at Midtown Middle school sold flowers as a fundraiser in September and October. In October, they charged $1.50 for

swat32

Let the price of flowers in September be x, then (100 + 20)/100 * x = $1.50
120/100 * x = $1.50
1.2x = $1.50
x = $1.50/1.2 = $1.25
The price of flowers in September is $1.25

Total money realised in September = $1.25 x 900 = $1,125
40% earned = 0.4 x $1,125 = $450

Total money realised in October = $1.50 x 700 = $1,050
40% earned = 0.4 x $1,050 = $420

The class earned more money in September and they earned $30 more than in October.
