A store offers a 14% discount on a DVD. If the cost is discounted by $4.90, what is the original cost of the DVD?

35

Step-by-step explanation:

Let's call the original price X

14% of x is equal to $4.90 to calculate 100% of the price we multiply 100 with 4.9 then divide it with 14

4.9 × 100 ÷ 14 = 35

answer: a numerical coefficient is a constant multiplier of the variables in a term. in the term -5x2y, the numerical coefficient is -5. in the expression ax2 + bx + c, the numerical coefficient of the x2 term is "a" and the numerical coefficient of the x term is "b".

step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
