DedPeter [7]

Answer:

The result when 78 is increased by 55% =  35.1

Step-by-step explanation:

Given:

No. = 78

Decrease% = 55%

To Find:

The result when 78 is increased by 55% = ?

Solution:

The result when 78 is increased by 55% = 78 - 55 x 78 / 100

The result when 78 is increased by 55% =  100 x 78 - 55 x 78 / 100

The result when 78 is increased by 55% =  78(100 - 55) / 100

The result when 78 is increased by 55% =  78 x 45 / 100

The result when 78 is increased by 55% =  3510 / 100

The result when 78 is increased by 55% =  35.1

Therefore,

The result when 78 is increased by 55% =  35.1

Terry goes to the store to buy a shirt. The original price is $32. The shirt is
Anton [14]

Answer:

The closest amount paid is $23

<em></em>

Step-by-step explanation:

Given

Price = \$32

Mark\ down = 20\%

Amount = 10% of Marked down price

Required

Determine the amount paid

First, we calculate the marked down price P2:

P_2 = Price(1 - Mark\ down)

Substitute values for Price and Mark down

P_2 = \$32 * (1 - 20\%)

Express percentage as decimal

P_2 = \$32 * (1 - 0.20)

P_2 = \$32 * (0.80)

Remove bracket

P_2 = \$32 * 0.80

P_2 = \$25.6

The payable amount is 10% off the marked down price,

This is calculated as:

Amount = P_2 - P_2 * 10\%

Substitute $25.6 for P2

Amount = \$25.6  - \$25.6* 10\%

Express percentage as decimal

Amount = \$25.6  - \$25.6* 0.10

Amount = \$25.6  - \$2.56

Amount = \$23.04

<em>The closest amount paid is $23</em>

Lin multiplies 7/8 times a number.the product is less than 7/8 . Which could be Lin’s number ?
igor_vitrenko [27]

Answer:

Any number less than 1

Step-by-step explanation:

Let x be the number Lin multiplies by 7/8. So, we have:

(7/8)*x < 7/8

We need to find the possible values for x. Lets start by dividing both sides of our inequality by (7/8) in order to get x alone on the left side.

(7/8)*x / (7/8) < (7/8)/(7/8)

Reordering:

(7/8) / (7/8) * x < (7/8)/(7/8)

As any number divided by itself (except from 0) is equal to 1:

x < 1

So, the number that Lin multiplied by 7/8 MUST be less than 1. This is evident, as any positive number multiplied by a number less than 1 will decrease, doesn't matter if its a negative or positive number.

So, such number is less than 1. Any number less than 1 could be Lin's number.
