The answer is 1224. You do 70.5 + 65.5, divided by two, then you take that answer and multiply by 18 to get 1224

75% increase followed by 50% decrease is it greater than to original
IceJOKER [234]

Answer:

  • Set original amount = x

<u>After a 75% increase, it would become</u>

x + 75%x = x + 0.75x = x(1 + 0.75) = 1.75x

<u>After a 50% decrease, it would become</u>

1.75x - 50%(1.75x) = 1.75x - 0.5(1.75x) = 1.75x - 0.875x = 0.875x = \frac{7}{8} x

Because \frac{7}{8} x is less than x, the new amount would be less than the original.

I need help if you get it right I will mark you
pav-90 [236]

Answer:

%30 off is the better price

Step-by-step explanation:

firstly we know that 2 - 12 is equal to 10 so that is $10.00 there from that coupon

to find out the second value, we first devide by the total amount (%100 in this case)

<em>12 / 100 = 10.12</em>

then we multiply by the partial amount (%30)

<em>0.12 * 30 = 3.6</em>

convert that into a dollar amount and we get the total discount in dollars

<em>3.60 = $3.60</em>

AND

<em>$3.60 > $2.00</em>

<em />

hope this helps ya, take care mate :D

Guessing you meant by a factor of 3... not 13 since none of the solutions are anywhere close to that.

to compress is to smoosh.
It's the equation of a line. If you smoosh it vertically the line becomes flatter and the slope smaller. 

Essentially g(x) = 3f(x)
3y = 12x + 6
y = (12/3)x + 6/3
y = 4x + 2
