$3.38

Step-by-step explanation:

Hello, I think I can help you with this.

you can solve this by using a simple rule of three

Step 1

the cost per minute is increased by 30%, it means you have to pay 130% of the original price, or you can find the 30% and add this value to the initial cost, it is exactly the same

if

$2.06 ⇔100 %

$x?  ⇔130%

do the relation and solve for x

so, the new price is $3.38.

Step 2

check finding the 30% and adding this value to the initial cost

$2.06 ⇔100 %

$x?  ⇔30%

do the relation and solve for x

$ 0.78+$2.6=$3.38

$3.38 =$3.38 ,ok

Have a good day.

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
