If you receive a 30% DISCOUNT off an item costing $60.00, how much money do you save?
NARA [144]

Answer:

Money saved  = $18

Step-by-step explanation:

Firstly, the term discount equals the difference between the price paid for and it's par value. Discount is a kind of reduction or deduction in the cost price of a product.

Given

Cost of an Item = 60$

Discount % = 30% on cost

Hence, Discount in $ = 60$*30%

                                   = 18$

Actual Cost = 60$ - 18$ = 42$

Therefore, Savings  = Discount

                    = 18$

Justine and Meagan played a trivia game. Justine answered a question incorrectly and lost 7 points. Then Meagan answered correct
Nataliya [291]

Answer:

m = -j, or in this case, m=-(-7)

Step-by-step explanation:

Assuming that Justine's score is represented by j and Meagan's score is represented by m, we know that j will always be the opposite of m.

To represent opposite, we put a negative sign before the variable.

This makes the current number, even if it's negative, the opposite value.

Let's test it out.

Since Justine's score is -7, substituting it into the equation makes it  m=-(-7). We know that two negatives make a positive, so m=7.

Now let's assume Justine's score is 7. Plugging it into the equation, we get m=-(7). That's the same thing as m = -1(7), and -1 times 7 is -7.

Hope this helped!

5. A pair of jeans costing
Levart [38]
So $39.50 is the price when you are paying full price, which can be represented by 100%. If you’re paying 25% less, than you are only paying 75% of the original price. Simply multiply $39.50 by 75%(expresses as 0.75) to determine the sale price. 39.50(.75)=29.62 The closest value to that is $29.50, so D is the answer.
