Melaniè has $660 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
• She buys a new bicycle for $471.21.
• She buys 4 bicycle reflectors for $14.58 each and a pair of bike gloves for
$32.40.
• She plans to spend some or all of the money she has left to buy new biking
outfits for $69.99 each.
Which inequality can be used to determine x, the maximum number of
outfits Melanie can purchase while staying within her budget?

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

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.
