Fred buys a binder for $4.50 and six reams of paper. Latasha buys an ink cartridge for $17.50 and four reams of paper. Both spen

kondor19780726 [428]

Answer:

The the price of one ream of paper is $6.5.

Step-by-step explanation:

Here, Let us assume the cost of one ream of paper = $ m

<u>The money spent by Fred:</u>

The money spent on a binder = $4.50

The money spent on 6 ream of papers = 6 x ( cost of 1 ream )

= 6 x ($m) = 6 m

⇒The total money Fred spent = Money spent on (binder + 6 ream of papers)

= 4.50 + 6 m ....... (1)

<u>The money spent by Latasha:</u>

The money spent on a cartridge = $17.50

The money spent on 4 ream of papers = 4 x ( cost of 1 ream )

= 4 x ($m) = 4 m

⇒The total money Latasha spent = Money spent on (cartridge + 4 ream of papers)

= 17 .50 + 4 m .... (2)

Also, Both spend the same amount of money

⇒4.50 + 6 m = 17 .50 + 4 m ( from (1) and (2))

or, 6 m - 4 m= 17. 50 - 4, 50

or, 2 m = 13

or, m = 13/ 2 = 6.5

So, the value of m = $6.5

Hence, the the price of one ream of paper is $6.5.

Meenu bought two fans for ₹1200 each. She sold one at a loss of 5% and the other at a profit of 10%. Find the selling price of e

Vinvika [58]

<h3><u>Solution: </u></h3>

Overall<u> </u>CP of each fan = ₹1200 .

One is sold at a loss of 5% .

( This means if CP is ₹100, SP is ₹95 ) .

• Therefore,When CP is ₹1200 , Then SP is ₹ 1140.

$= > \frac{95}{100} \times 1200 = 1140$

Also,Second fan is sold at a profit of 10% .

It means , If CP is ₹100 , SP is ₹110.

Therefore , When CP is ₹1200 , Then SP is ₹1320.

<u>• We need to find the combined CP and SP to say whether there was an overall profit or Loss.</u><u>.</u>

Total CP = ₹ 1200 + ₹ 1200 = ₹ 2400.
Total SP = ₹ 1140 + ₹ 1320 = ₹ 2460.

Since total SP > total CP , A profit of ₹ ( 2460 - 2400 ) or ₹60 has been made ..
