You are running a concession stand at a basketball game. You are selling hot dogs and
.
sodas. Each hot dog costs $4 and each soda costs
$1.75. At the end of the night you made a total of
$201. You sold a total of 75 hot dogs and sodas
combined. You must report the number of hot
dogs sold and the number of sodas sold. How many
hot dogs were sold and how many sodas were sold?
a

true

step-by-step explanation:

b

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.
