Answer:

Brand B is the BEST buy.

Step-by-step explanation:

To find the cheapest Brand we will find the price of one bandaid of each brand.

Brand A : 20 for $2.5 ⇒ $0.125 for one bandaid.

Brand B : 35 for $3.25 ⇒ $0.093 for one bandaid

Brand C : 50 for $5.25 ⇒ $0.105 for one bandaid

Brand D : 100 for $10 ⇒ $0.100 for one bandaid

So the best price to purchase will be Brand B.

A taxi driver had 50 fares to and from the airport last Monday. The price for a ride to the airport is $10, and the price for a
Rina8888 [55]

Answer:

Number of Fares to airport is 25 and number of fares from airport is 25.

Step-by-step explanation:

Given:

Total Number of fares =50

Let number of fares to airport be x.

Let number of fares from airport be y.

hence the equation can be framed as;

x+y=50 \ \ \ \ equation \ 1

Also Given

Total Money Collected = $375

Cost to airport = $10

Cost from Airport = $5

Total Money Collect is equal to Cost to airport multiplied by number of Fares to airport plus Cost from airport multiplied by number of Fare from airport.

10x+5y=375

Dividing by 5 on both side we get;

2x+y = 75 \ \ \ \ equation \ 2

Now Subtracting equation 1 from 2 we get;

(2x+y)-(x+y)=75-50\\2x+y-x-y=25\\x=25

Substituting the value of x in equation 1 we get;

x+y=50\\25+y=50\\y=50-25\\y=25

Hence Number of Fares to airport is 25 and number of fares from airport is 25.

Peter is writing a number in scientific notation.The number is grater that ten million and less that one hundred million.Which e
OLga [1]

Answer:

M  =  a \times 10^7  where 1 < a ≤ 9

The EXPONENT USED BY PETER is 7 in all the possible cases.

Step-by-step explanation:

Let us assume the needed number is M.

Also, given:

The needed number is GREATER than 10 Million.

⇒ M  > 10 Million

⇒ M > 10,000,000

⇒ M > 1 \times 10^7  ...... (1)

The needed number is SMALLER than 100 Million.

⇒ M  <  100 Million

⇒ M < 100,000,000

⇒ M  <  1 \times 10^8  ...... (2)

Comparing (1) and (2) we can see that M can have more than 7 zeroes after 1 but LESS than 8 zeroes after 1.

So, the possible values of M can be:

M  =  a \times 10^7  where 1 < a ≤ 9

So, the EXPONENT USED BY PETER is 7 in all the possible cases.
