You are ordering softballs for two softball leagues. The Pony Leagues uses an 11-inch softball prices at $2.75. The Junior Leagu

Zigmanuir [339]

Answer:

I have ordered 30 softballs of 11-inch and 50 soft balls of 12-inch.

Step-by-step explanation:

Let the number of 11-inch softball be 'x'.

Let the number of 12-inch softball be 'y'.

Given:

Total number of soft balls = 80

Now we know that.

Total number of soft balls is equal to sum of the number of 11-inch softball and the number of 12-inch softball.

framing in equation form we get;

$x+y=80 \ \ \ \ equation \ 1$

Also Given:

Price of 11- inch softball = $2.75

Price of 12-inch softball = $3.25

Total Bill = $245

Now we know that;

Total bill of soft balls is equal to sum of Price of 11- inch softball multiplied by the number of 11-inch softball and Price of 12- inch softball the number of 12-inch softball.

framing in equation form we get;

$2.75x+3.25y = 245 \ \ \ \ equation \ 2$

Now Multiplying equation 1 by 3.25 we get;

$3.25(x+y)=80\times 3.25\\\\3.25x-3.25y = 260 \ \ \ \ equation \ 3$

Now Subtracting equation 2 from equation 3 we get;

$(3.25x+3.25y)-(2.75x+3.25y)=260-245\\\\3.25x+3.25y-2.75x-3.25y = 15\\\\0.5x = 15$

Dividing both side by 0.5 we get;

$\frac{0.5x}{0.5}= \frac{15}{0.5}\\\\x= 30$

Now Substituting the value of 'x' in equation 1 we get;

$x+y=80\\\\30+y=80\\\\y =80-30 =50$

Hence I have ordered 30 softballs of 11-inch and 50 soft balls of 12-inch.

A health food store was charging $5.40 for a small salad but raised the price 8% the new price after the increase is $5.83 enter

joja [24]

Answer:

New price= Increament + old price

Step-by-step explanation:

Given data

Old price = $5.40

Percent increase= 8%

New price= $5.83

Let find the increment

=8/100*5.40

=0.08*5.40

=$0.432

New price= Increament + old price

New price=0.432+5.40

New price=$5.83

Simplify the following polynomial and write the answer in standard form. (-2x^3+5x^2-4x+8)-(-2x^3+2x-3)

Masja [62]

$(-2x^3+5x^2-4x+8)-(-2x^3+2x-3)\\\\=-2x^3+5x^2-4x+8-(-2x^3)-2x-(-3)\\\\=-2x^3+5x^2-4x+8+2x^3-2x+3\\\\=(-2x^3+2x^3)+5x^2+(-4x-2x)+(8+3)\\\\=5x^2-6x+11$
