A garden centre has reduced the price of all plant pots by 20%. Jane bought a reduced plant pot for £40. How much would she have paid for this plant pot before the price reduction?

Answers

She paid 80% of the regular price because it was 20% off so...

80% = £40

We want to get to the regular price (100%) so...

100% = £40 x 100/80 = £50

answer: £50

Answer:he paid 80% of the regular price because it was 20% off so...

80% = £40

We want to get to the regular price (100%) so...

100% = £40 x 100/80 = £50

answer: £50

Solve the following: -3x + 7(x + 5) = 5x + 38

Answers

Answer: -3

Step-by-step explanation:

-3x+ 7x+ 35= 5x + 38

You solve the distributive property on the left side and set it equal to the right

4x+35= 5x+38

-4x -4x

35= x+38

-38 -38

Anthony found a number that is 20% of 30% of 400 what percent of 45 is the number that Anthony found

Answers

For this case we have:

1st step:

We look for 30% of 400 by a rule of three of the form:

400 -------> 100%

x -----------> 30%

Where x is given by the number that represents 30% of 400.

We have:

$x =((30 * 400))/(100)\nx = 120$

2nd step:

We search for 20% of the number found, that is, $x = 120$ , using a rule of three:

120 -------> 100%

y -----------> 20%

Where y is given by the number that represents 20% of 120.

We have:

$y =((20 * 120))/(100)\ny = 24$

So, the number that Anthony found is 24.

3rd step:

According to the statement, we must find the% that represents the number of Anthony, based on the number 45. Through a rule of three we have:

45 -------> 100%

24 -----------> z%

Where z is given by the% that represents Anthony's number, knowing that 45 represents 100%.

We have:

$z =((24 * 100))/(45)\nz = 53.33$ %

Answer:

The number of Anthony represents 53.33% of 45.
