Lily made $75.36 more than Layla did. If Layla raised her price to $1.00, she would still not make more money than Lily.

Use a proportion to find the number of cupcakes Lily makes in 8 hours. She bakes 7 cupcakes in 10 minutes; we want to know how many she makes in 8(60)=480 (since there are 8 hours and each hour is 60 minutes):

7/10 = x/480

Cross multiply:
7*480 = 10*x
3360 = 10x

Divide both sides by 10:
3360/10 = 10x/10
336 = x

Lily bakes 336 cupcakes.

She sells 2/3 of these; 2/3(336) = 2/3(336/1) = 672/3 = 224 cupcakes sold.

Each cupcake is sold for $1.29; 224(1.29) = 288.96

To find the number of cupcakes Layla makes in 8 hours, we set up a different proportion. We know she bakes 8 cupcakes in 12 minutes; we want to know how many she bakes in 8(60) = 480 minutes:

8/12 = x/480
8*480 = 12*x
3840 = 12x

Divide both sides by 12:
3840/12 = 12x/12
320 = x

She bakes 320 cupcakes. She sells 75% of those; 75% = 75/100 = 0.75:
0.75(320) = 240

Each of those 240 cupcakes sells for $0.89:
0.89(240) = 213.60

This means Lily makes 288.96-213.60 = 75.36 more than Layla.

If Layla raised her price to $1.00, she would make 1(240) = $240; this is still less than Lily.

Answer:

127 if it says to use 3.14, 200 if it does not ask to use 3.14

Step-by-step explanation:

C= $2\pi r$

Substitute C for 400

400=2*r

400=2r

divided both sides by 2

A neighborhood was given a vacant lot in the shape of a rectangle on which to build a park. The base of the lot is 72.2 feet and

Darya [45]

Answer:

We are given a rectangular lot with dimensions 72.2 feet long and 50 feet wide.

1. To find the size of the park, we need to find the AREA of the rectangular lot.

Area of a rectangle = Length × Width

i.e. Area of a lot = 72.2 × 50

i.e. Area of a lot = 3610 feet²

Thus, the size of the park is 3610 feet².

2. To find the amount of fencing needed, we need to find the PERIMETER of the rectangular lot.

Perimeter of rectangle = 2 × ( Length + Width )

i.e. Perimeter of the lot = 2 × ( 72.2 + 50 )

i.e. Perimeter of the lot = 2 × 122.2

i.e. Perimeter of the lot = 244.4 feet.

Thus, the amount of fencing needed for the park of the park is 244.4 feet.
