from 1970 to 1980 the consumer price index increased from 38.8 to 82.4. If a container of onion dip cost $0.48 in 1970 and the p
Vikki [24]
We need to find the percent increase from 38.8 to 82.4, so

x * 38.8 = 82.4
x = 82.4/38.8
x = 2.1237

Multiply by 100 to convert to percentage (move decimal 2 places to the right)

2.1237 = 212.37%

Now we can apply this percentage increase to the onion dip...

0.48 x 212.37% =
0.48 x 2.1237 = 1.019 
 
Round to the nearest cent $1.02 is the amount of increase.  Now add it to the original price to get today's price...

$1.02 + .48 = $1.50

I’ll give you fat points
Bogdan [553]

Answer:

  • See below

Step-by-step explanation:

<u>Multiply and simplify:</u>

  • (x - 1)(x + 2)(x + 3) =
  • (x² + 2x - x -2)(x + 3) =
  • (x² + x - 2)(x + 3) =
  • x³ + 3x² + x² + 3x - 2x - 6 =
  • x³ + 4x² + x - 6

<u>From the final polynomial we can see that:</u>

  • a = 1, b = 4, c = 1 and d = - 6

So all the coefficients are positive but the constant d is negative

Solve this equation: 2s + s + 12 = 132. <br> A. s = –30<br> B. s = 120<br> C. s = 9<br> D. s = 40
nataly862011 [7]
Solve your equation step-by-step.

2s+s+12=132

Simplify both sides of the equation.

2s+s+12=132

Simplify:

3s+12=132

Subtract 12 from both sides.

3s+12−12=132−12

3s=120

Divide both sides by 3.

3s/3 = 120/3

s=40
