A department store sells a pair of shoes with an 87% markup. If the store bought the pair of shoes for $55.25, what is the selli

Markup means they sell it for that percentage more than they bought it for. First let's calculate how much they will mark it up for:

\sf 55.25\cdot 87\%

Convert 87% into a decimal(87/100):

\sf 55.25\cdot 0.87

Multiply:

\sf\approx 48

This is how much they'll mark it up, now let's add it to how much they bought it for to find out the selling price:

\sf 48+55.25\approx\boxed{\sf \$ 103}

On a certain hot​ summer's day, 477 people used the public swimming pool. The daily prices are 1.50 for children and 2.25 for ad
Akimi4 [234]

Answer:

212 children, and 265 adults

Step-by-step explanation:

To find the number of children and adults, we can set up a systems of equations.

x= number of children

y= number of adults

Equation 1: Price

1.50x+2.25y=914.25

Equation 2: Total number of people

x+y=477

Now, let's solve the equation using substitution.

Rearrange the second equation to solve for one variable.

x+y=477

x=477-y

Now plug x equals into the first equation, and solve for y.

1.50x+2.25y=914.25

1.50(477-y)+2.25y=914.25

715.5-1.50y+2.25y=914.25

715.5+0.75y=914.25

0.75y=198.75

y=265

We just solved for the number of adults. Now let's plug y equals into the second equation to find the number of children.

x+y=477

x+265=477

x=212

Plese i need help on this one !!!!!!!
patriot [66]

Answer:

I got 32.

Step-by-step explanation:

I used the Pythagorean theorem to find the lengths of the width and length. The length between (-1, 4) and (3, 3) was approximately 4 in. The distance between (-1, 4) and (-3, -4) was approximately 8 in. I then used those numbers to find the perimeter ((2*4)+(2*8))
