A) Original price : y =10.x
Cheaper brand : y = 7x
The original box is $3 more than the cheap one. Proof:
Suppose 1 box is bought of each (x=1),original will cos10 & the cheaper $7
b) Each time he buys a cheap brand he save $3 ($10-$7), on 5 cheap boxes, he would save $3 x 5 boxes = $15
<u><em>251.5</em></u> is the answer!
Why? :
Plug in 6 as 'x' :
35.25(6) + 40 = ?
Solve and you get 'y'. That is the answer!
<em>Hope this helps!</em>
Answer:
Compound Interest= $3440
Final Amount= $5440
Step-by-step explanation:
Compound Interest's formula= P(1+r/100)^n
where P is Principal, r is Rate then n is Years
So in this case,,2000(1+.72)^1 = $3440
Hence, Total Amount = Principal+Interest
therefore T.A= $2000+$3440
T.A=$5440
