Shania wants to purchase a book bag with an original price of $28. 0. She also bought a necklace for $35. 75. There is a storewi
omeli [17]
Answer:
$24.36 for the bookbag if they tax the original price
$23.97 if they tax the sales price
$31.10 for the necklace if they tax the original price
$30.60 if they tax the sales price

So an overall of $55.46 was spent for a taxing of the original price and an overall of $54.57 was spent for the taxing of the sales price.

Step-by-step explanation:
20% of $28.00 is $6.60, subtract $6.60 from $28.00 and you'll get $22.40.
7% of $28.00 is $1.96, add $1.96 to $22.40 and you'll get $24.36 (for taxing of the original price). If you want the taxing of the sales price then you'd do 7% of 22.40 which is $1.57, add that to $22.40 and you get $23.97

Then you do the same for the necklace:
20% of $35.75 is $7.15, subtract $7.15 from $35.75 and you'll get $28.60.
7% of $35.75 is $2.50, add $2.50 to $28.60 and you'll get $31.10 (for taxing of the original price). If you want the taxing of the sales price then you'd do 7% of 28.60 which is $2.00, add that to $28.60 and you get $30.60
Add the final numbers and you'll get your overall.

Hope this helps

10. A home improvement store advertises 60
Dima020 [189]

Answer:

cost for (not per) 1 sq ft. floor: $84.79

y = total costs

x = sq ft of flooring

y = x4.79 + 80.00

Step-by-step explanation:

i this equation, y = the total cost wile x = square ft. of flooring

to find out the price when we know that 60 sq ft is $287.00 without the instalation fee, all we have to do is divide 287.00 by 60

287 / 60 = 4.79

so we now know how much 1 sq ft. costs, but to implament it into an equation we need to multiply it by the amount of flooring, so we let x be the number of sq ft used

now all we have to do is add the instalation fee, no, we literally add it in the equation at the end, so that it is added after we multiply by sq ft (not before) then after we calculate that, we get the total cost for x sq ft of flooring, or y

hope this answers your question
