Makena buys some candy and a Red Bull. The candy is priced by the ounce. The equation y = 1.75x + 2.50 can model the total cost of Makena 's purchases. What
does the value of the function at x = 0 represent?
x O ?
A The cost of the Red Bull and x ounces of candy.
B The cost of the Red Bull and 1 ounce of candy.
C The cost of the candy.
D The cost of the Red Bull.

the answer is true.

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.

ok thats very interesting
