A bakery used 38 pounds of flour to make French bread and
fomenos

Answer:

since we are not given the options, I will write down a few equations that represent the number of French bread loaves and bagels:

  • a = number of loaves of French bread
  • b = number of bagels
  • available amount of flour = 38

2a + b ≤ 38

2a ≤ 38 - b

a ≤ (38 - b) / 2

a ≤ 19 - 0.5b

b ≤ 38 - 2a

b ≤ 2(19 - a)

Hopefully one of these equations is one of the choices given to you.

Find the deference between
maxonik [38]

Answer:

$5520

Step-by-step explanation:

Given data

Principal=  $24000

Rate=10%

time= 2 years

Firstly, the compound interest is given as

A=P(1+r)^t

A=24000(1+0.1)^2

A=24000(1.1)^2

A=24000*1.21

A=$29040

The simple interest is given as

A=P(1+rt)

A=24000(1+0.1*2)

A=24000(1.2)^2

A=24000*1.44

A=$34560

Hence the difference is

=34560-29040

=$5520
