Answer:
2/15 fraction of money is spend to buy magazine.
Step-by-step explanation:
Total Money given by Evan's uncle = $30
Money spent by Evan to buy magazine = $4
Fraction of money spend on magazine = Money spent by Evan to buy magazine ÷ Total Money given by Evan's uncle
⇒ 4/30 = 2/15
Hence 2/15 fraction of money is spend to buy magazine.
lets check our answer.
2/15 of Total Money given by Evan's uncle = (2/15 )× 30 = 2 × 2 = 4
so $4 represents 2/15 of $30 , hence our solution is correct .
For the answer to the question above, <span>f x is the number of days she works, she'll earn $90x </span>
<span>After buying the laptop, she'll have $90x - $700 left over, which will pay for ($90x - $700) / $150 days of travel. So we have y = ($90x - $700) / $150 = (9x - 70) / 15 = 0.6x - (14/3) </span>
<span>Note that y can't be negative. Also, if y = 0, then Emma doesn't get to travel at all, so we should avoid that. So we have: </span>
<span>0.6x - (14/3) > 0 </span>
<span>0.6x > 14/3 </span>
<span>x > (14/3) / 0.6 </span>
<span>x > 70/9 </span>
<span>The question says that x can be up to 40, so the domain is 70/9 < x <= 40 </span>
<span>That's approximately 7.777... < x <= 40 </span>
<span>Multiply those numbers by 0.6 and then subtract 700 to get the range: </span>
<span>0 < y <= 58/3 </span>
<span>That's approximately 0 < y <= 19.333</span>
