The chart below lists the original and sale prices of items at a clothing store. Clothing Prices Original price Sale price $7.99 $5.59 $10.99 $7.69 $12.99 $9.09 $15.99 $11.19 $24.99 $17.49 $29.99 $20.99 Which statement best describes why the sale price is a function of the original price? As the original price increases, the sale price also increases. The sale price is always less than the original price. For every original price, there is exactly one sale price. The sales price is never less than zero.

Which statement best describes why the sale price is a function of the original price? C. For every original price, there is exactly one sale price.

This is correct! :)

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.

i think it’s a i believe
