Suppose you are a florist. A customer purchases a flower bouquet for $36 and a box of chocolates for $18. The customer has a 20% off coupon, and you calculate the total price after 8.25% tax to be $46.80.

$46.80

Step-by-step explanation:

Selling prices

Flower bouquet = $36

Chocolate box = $18

Total Purchases = $36 + $18 = $54

20% Coupon discount on purchases = $54 x 20$ = $10.8

Purchases net of discount  = $54 - $10.8 = $43.2

Tax on purchases = 43.2 x 8.25% = $3.6

Total Price inclusive of tax = $43.2 + $3.6 = $46.8

Hence proved that the total price after 8.25% tax to be $46.80

$46.80 is the total price

8.25% tax paid

Step-by-step explanation:

Price of flower purchased is $36

Price of chocolate purchased is $18

Total amount of things bought is 18+36= 54

The customer has a 20% off coupon.

= 20/100×54= 10.8

The amount paid with 20% off is now:

54-10.8= $43.2

Tax on purchases will be 8.25/100 × 43.2 = 3.564

The amount paid will now be 43.2+3.564= $46.764

From the above, it is definitely true that the percentage tax on purchases is 8.25

x+y=15 the total of 15 pounds

(6x+9y)/15=7 the average of each pound out of 15 that is valued $7

(6x+9*(15-x))/15=7

(6x+135-9x)/15=7

(135-3x)/15=7

135-3x=7*15

135-3x=105

-3x=-30

x=10

deduce that y=15-10=5

so basically, you can conclude that 10 of the 1st candies are valued at 60$ and 5 pound of the second will be valued at at $45 which adds up to $105

and 105/15=7 which shows us that we were right and overall 15 pounds has and average pound value of $7

hope this : )
