Angel lives in Florida, which has a sales tax of 6%. He just bought some word-
processing software whose full price was $90, but he presented the retailer
with a coupon for $30, which the retailer accepted. What was the total
amount that Angel paid?
O
O
A. $60.00
B. $65.40
C. $63.60
D. $95.40

Option B

$65.4

Step-by-step explanation:

Imposing 6% tax on the full price would mean the final amount that should be paid will be equal to 106% of the full price, also expressed as 1.06 and this is equivalent to 1.06*90=$95.4.

However, since there's a coupon then the payment will be less the value of coupon. Therefore, final payable amount will be 95.4-30=$65.4

based on context clues you gave i'm assuming the answer would be c.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
