Answer:
Yes, Mark has $16 left and only has to pay his sister $15.
Step-by-step explanation:
1/5=x/20
use cross multiplication to find (x),which represents 20% of 20.
x/20=1/5 (cross multiply)
20=5x (divide by 5 on both sides)
x=4
This tells you that Mark gave $4 to the local charity.
20-4=16
Subtracting 4 from his original amount, he now has $16 left.

- <u>E</u>xponents
- <u>M</u>ultiplication
- <u>D</u>ivision
- <u>A</u>ddition
- <u>S</u>ubtraction
Solve:
**Disclaimer** I assume that it is supposed to be (25 + 45). If it was, then you may refer to my answer. If the ")" after 45 is just a typo, you may point it out and I will redo it.
<u>Given expression</u>
13 + {16 + 2 - [(25 + 45) × 3] + 9}
<u>Do the parenthesis of the inner most</u>
=13 + {16 + 2 - [70 × 3] + 9}
=13 + {16 + 2 - 210 + 9}
<u>Do addition first, then subtraction</u>
=13 + {18 - 210 + 9}
=13 + {27 - 210}
=13 - 183
=-170
Hope this helps!! :)
