the students at midtown middle school sold flowers as a fundraiser in september and october. in october, they charged $1.50 for each flower. the october price was a 20% increase of the september price.

part a:

what was the price of the flowers in september?

part b:

the seventh-grade class earned 40% of the selling price of each flower.

in september, they sold 900 flowers.

in october, they sold 700 flowers.

did they earn more money in september or october?

how much more?

Part A:

answer- $1.80

(20% of $1.50 is .30, so    1.50+.30=1.80)

Part B:

September=$540 ( 1.50 times 900 is 1,350, 40% of 1,350 is 540)

October=$504     ( 1.80 times 700 is 1,260, 40% of 1,260 is 504)

answer=they earned more money in September; $36 more

(540-504=36)

Hope this helped!

what do you need me to answer?

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
