1. A 13-ounce package of pistachios costs $5.99. Problems 2-4. Find the unit rate to the nearest cent per ounce. Compare.
2. A 24-ounce box of cornflakes costs $4.59.
3. A 36-ounce box of cornflakes costs $5.79.
4. Which box is the better buy?

1)

1) 1 ounce costs 46 cents. 2) 1 ounce  of cornflakes costs 19 cents ( 0.19125).

3) 1 once cornflakes is 16 cents (0.1608) ( 36-ounces). 4) The 36 ounce box is a better buy.

Step-by-step explanation:

Divide the cost by the number of x units to find the cost of one unit. You are welcome.

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.
