When a problem says that the price was increased by 100% + n%, it means you add on n% percent of the original price. In this problem, the original price was $35. The new price is 115% percent of the original price. So all we need to do is find 15% of the original price and add it onto the original price to find the new price.
$35 * 0.15 = $5.25
$35 + $5.25 = $40.25
The new price of the shoes is $40.25.
Answer:
240 - 5x and the candle will be at 0 mm in 48 seconds
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
A 240 mm candle is burning and shrinks in height 5mm per second
<em>240 - 5x</em>
<u>Step 2: If needed solve for x</u>
240 - 5x - 240 = 0 - 240
-5x / -5 = -240 / -5
<em>x = 48</em>
Answer: 240 - 5x and the candle will be at 0 mm in 48 seconds
Graph Below: (0, 240) shows the initial start and (48, 0) shows the ending point
I=PRT
r=rate in percent
t=time in years
p=principal
convert percent to decimal
assuming you means at 7%
percent means parst out of 100
7%=7/100=0.07
so ow we have
p=8000
r=0.07
t=5
i=8000 times 0.07 times 5
I=40000 0.07
I=2800
interest=$2800
Answer:
20
400 is 20 square= 20*20
so 20 students in each row
-37m = 12 so u take -37 + 37 = 0 > m = 12 + 37 > m = 49 which isnt one of the choices... u cant divide it and if u do -37 + 12 = -25 that isnt one of the choices either
