$56 they are 25% off wants to know what is the discount price

$42

Step-by-step explanation:

This is an example of a percentage decrease.

To work out the percentage decrease you would first need to convert the percentage of 25% into a decimal. You can do this by dividing the percentage  of 25 by 100, this gives you 0.25. This is because percentages are out of 100.

The next step is to minus 0.25 from 1, this gives you 0.75. This is because we are working out the percentage decrease.

To work out the discounted price you would multiply the amount of $56 by 0.75, this gives you $42.

1) Divide 25 by 100.

2) Minus 0.25 from 1.

3) Multiply $56 by 0.75.

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
