A camera shop purchases a camera for $56.98 and sells it for $102.56. What is the percent of markup?

Amiraneli [1.4K]

Answer:

180%

Step-by-step explanation:

Set up an equation:

Variable x = percent of markup

102.56/56.98 = x/100

Cross multiply

102.56 × 100 = 56.98 × x

10,256 = 56.98x

Divide both sides by 56.98:

179.99297.... = x

Round to nearest whole number:

180 = x

Check your work:

56.98 × 180%

Convert the percentage into a decimal:

56.98 × 1.80

102.564

Round to nearest cent:

102.56

Correct!

A card is drawn from a well shuffled deck of 52 cards. Find the probability that the card is a red card or a 2.

tamaranim1 [39]

$|\Omega|=52$

There are 26 red cards and four 2's. But two 2's are red, so $|A|=26+4-2=28$

$P(A)=\dfrac{28}{52}=\dfrac{7}{13}\approx54\%$

A kite has a height of 36 inches and a width of 30 inches. Explain how to use the area formula for a triangle to find the area o

mote1985 [20]

Height of the kite is = 36 inches.

Width of the kite is = 30 inches

One of the ways to find the area is to draw a vertical line to break the kite into two equal triangles. Mark the base as 36 inches and height as 15 inches .

Now we will use the formula $area=\frac{1}{2}*base*height$ to find the area of each triangle. Then we will add both the areas to find the area of the kite.
