Step-by-step explanation:
based on the story told I expected completely different questions.
but for the actually asked question the whole thing about gaining our not gaining weight is competent irrelevant. ignore it.
so, all we need to do is looking at the row totals.
27.4% of the participants took 1 vitamin.
49.5% of the participants took more than 1 vitamin.
so, 49.5% + 27.4% = 76.9% of all participants are taking vitamins in some form.
therefore, the second answer option is correct.
Answer:
The total amount a member pays for an item with a regular price of x dollars is T (x) = 0.963<em>x</em>.
Step-by-step explanation:
Key points:
- Discount is subtracted from the regular price of an item.
- Sales tax is added to the regular price of an item.
It is provided that the customers receive a 10% discount if they are members and all customers must pay 7% in sales tax.
Two functions are provided are:
f (x) = 0.90<em>x </em>; the price of an item after the 10% member discount
g (x) = 1.07<em>x </em>; the total amount customers pay for a purchase after sales tax is applied.
Compute the total amount a member pays for an item with a regular price of x dollars as follows:
T (x) = Discount × Sales Tax
= 0.90 × 1.07 × <em>x</em>
= 0.963<em>x</em>.
Thus, the total amount a member pays for an item with a regular price of x dollars is T (x) = 0.963<em>x</em>.
Step-by-step explanation:
In this question we need to decrease 216 by 
or 37.5 %.
For this, firstly find 37.5 % of 216.
Now subtracting 81 from 216 to find decrease of 216 by 37.5 %.
So,
216-81 = 135
Hence, 135 is the decrease of 216 by 37.5 %.
