Answer: 0.04 per pound

Step-by-step explanation:

A 5 pound bag of apples costs 4.50.

The unit price will be 4.50 divided by 5 which will be:

4.50 ÷ 5 = 0.9

The unit price is 0.9 per pound

A 8 pound bag of the same type of apples costs 7.52.

The unit price will be 7.52 divided by 8 which will give:

7.52 ÷ 8 = 0.94

The unit price is 0.94 per pound

The difference in the unit prices will be the subtraction of 0.90 from 0.94.

0.94 - 0.90 = 0.04

The difference in the unit prices is 0.04 per pound.

____ [38]

Answer:

r=4\frac{3}{8}

Step-by-step explanation:

Given the following question:

4\frac{5}{8} +r=9

<u>Rewrite the expression to find the value of r:
</u>
9-4\frac{5}{8}

<u>Subtract by finding the common denominator:</u>
9-4\frac{5}{8}
9=\frac{9}{1}
4\frac{5}{8} =8\times4=32+5=37=\frac{37}{8}
\frac{9}{1} -\frac{37}{8}
\frac{9}{1} \times8=\frac{72}{8}
\frac{37}{8} \times1=\frac{37}{8}
\frac{72}{8} -\frac{37}{8}
72-37=35
=\frac{35}{8}
\frac{35}{8} =35\div8=4\frac{3}{8}
r=4\frac{3}{8}
4\frac{5}{8} +4\frac{3}{8} =9

Hope this helps.

Can someone help me with question 3

2. Alana needs to sell 52 boxes of cookies:

She sold 7 boxes to her aunt

She sold 2 boxes to her mother

She sold 15 boxes to her neighbor

you add 7+2+15 = 24 boxes of cookies that she sold

We need to find out how many more boxes of cookies she needs to sell-

We take the 24 boxes she sold and subtract from 52 boxes that she needs to sell.

24 - 52 = 30

The answer is 30, she needs to sell 30 more boxes.

3.  Sam, Jimmy and Andre shared a number of pennies in the ratio 8:5:3

Sam (8), Jimmy (5) and Andre (3)

How many more pennies did Jimmy receive than Andre?

you subtract 3 - 5 = 2

The answer is 2 more pennies.

-------------------------------------------------------------------------------------------------------------

4. Jamila spent $33.00 and Akiko spent $ 42.00  

Jamila  had 4 times as much money left as Akiko. How much money did each of them have in the beginning?

Since Akiko spent the highest amount- you will have to go with the higher amount to find the answer

4 x $42.00 = $168.00

They both in the beginning had $168.00

I hope this helps.

30% of number A is the same as 40% of number B. what could A and B ? <br><br>​
Sunny_sXe [5.5K]

9514 1404 393

Answer:

  A = 4, B = 3

Step-by-step explanation:

You require that ...

  0.30 × A = 0.40 × B

Then ...

  B = (3/4)A . . . . . divide by 0.40

Any pair of numbers that satisfies this equation will be possible values of A and B. One such pair is (A, B) = (4, 3).
