Jazeer opened a lemonade and cookie stand after investing $75 for supplies, including 5 gallons of lemonade and 10 dozen cookies. During the first 3 hours, jazeer sold lemonade for $3 per 16-ounces and cookies for $2 each. Over the next 2 hours, jazeer sold the lemonade for $2 each and the cookies for $1 each until everything was sold. What is the total of number of items (lemonades and cookies combined) that jazeer sold?

answer;

the correct answer

just use google you beautiful person.

have a nice day < 3

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.
