Agroup of tourists spends $156 to rent snorkels and fins. a total of 15 snorkels and 18 pairs of fins are rented. renting a snorkel costs four times as much as renting a pair of fins. how much does it cost to rent a snorkel?

Step-by-step explanation:

Givens:

The problem specifies that a snorkel costs four times as much as a pair of fins, that is:

snorkels.

fins.

The equation that represents the total cost is:

Now, we just have to substitute the expression for snorkels in the total cost equation:

Then,

Therefore, a snorkel's rent costs $8.

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.
