Ahmed, Walid and Faisal made $1446 profit from selling used books. If Ahmed to receive double amount of Faisal and Walid to rece

crimeas [40]

Answer:

Faisal receives $241

Ahmed receives $482

Walid receives $723

Step-by-step explanation:

I am going to build a system of equations to solve this question.

We have that:

x is the amount that Faysal received.

y is the amount that Ahmed received.

z is the amount that Walid received.

Ahmed, Walid and Faisal made $1446 profit from selling used books.

This means that

$x + y + z = 1446$

Ahmed to receive double amount of Faisal

This means that $y = 2x$

Walid to receive triple amount of Faisal.

This means that $z = 3x$

$x + 2x + 3x = 1446$

$6x = 1446$

$x = \frac{1446}{6}$

$x = 241$

$y = 2x = 2*241 = 482$

$z = 3x = 3*241 = 723$

Faisal receives $241

Ahmed receives $482

Walid receives $723

noname [10]

Answer: 7

Step-by-step explanation:

Given : The recommended daily allowance for vitamin c is 60 mg per day .

Then, for one whole week , the recommended allowance for vitamin c will be :-

$7\times60=420\text{ mg}$

Also, there are 70 mg of vitamin C per 100 g orange.

1 g = 1000 ml

The proportion of Vitamin C in 100 g = $\dfrac{70}{100000}=0.0007$

1 oz =28.3495 grams

Then, $3\ oz= 3\times28.3495=85.0485 \text{ gm}=85048.5\ mg$

Then, amount of vitamin C in 85048.5 mg = $0.0007\times85048.5=59.53395\approx59.53\ mg$

Then, the number of oranges have to eat each week to meet this requirement= $\dfrac{420}{59.53}\approx7$

Hence, about 7 oranges you would have to eat each week to meet this requirement.
