There is a vendor at a carnival selling bags of cotton candy. Each bag of cotton candy has the same cost. She starts each day wi

umka21 [38]

Answer:

The cost of each cotton candy bag is $4.

Step-by-step explanation:

Consider the provided information.

Let, the vendor has $x$ dollar at the starting of each day.

Let, the cost of each cotton candy bag is $y$ .

Now when she sells a total of 12 bags, she has $128.

$x+12y=128$ .....(1)

After she sells a total of 20 bags, she has $160.

$x+20y=160$ ....(2)

Subtract equation 1 from equation 2.

$(x+20y)-(x+12y)=160-128$

$8y=32$

$y=4$

Hence, the cost of each cotton candy bag is $4.

The scale drawing of a backyard includes a tennis court 10cm x 5.5cm. If the drawing has a scale

Natasha2012 [34]

Step-by-step explanation:

2.5 m = 250 cm

so, the scale factor is 1/250

that means the tennis court is in reality

10×250cm × 5.5×250cm = 2500 × 1375 = 3,437,500 cm²

1 m² = 100×100 = 10,000 cm²

so,

3,437,500 cm² = 343.75 m²
