Calculate the total cost of an item bought at a negotiated price of $15,640 and a $2,500 trade-in-allowance. The sales tax is 7.
Fofino [41]
Hey! :)

The total cost of the item is the second choice which is $14,372.08. I arrived to the answer by simply: 
1) multiplying the sales tax to the negotiated price (15640*.072 = 1126.08) 
2) adding the sales tax to the negotiated price and the registration as well (15640+1126.08+106= 16872.08)
3) subtracting the trade in allowance from the computed value (16872.08 - 2500 = 14372.08)
Hope this helps! :)

V1/V2=T1/T2. Solve for V1
Ahat [919]
V1=(T1/T2)*V2
In this problem, since you are given no actual numbers, the only thing you can do is multiply V2 over to get V1 alone. Since you can't cancel anything out, you are left with the answer above.

algol13

Answer:

8x = 104

x = 13

Step-by-step explanation:

Since we are trying to distribute it evenly, we divide 104 by 8 to get 13 pieces of candy per child.

The equation is saying 8 kids times <em>x</em> amount of candy per kid is equal to a total amount of 104 pieces of candy.
