Answer:
mary=10 jack=15
Step-by-step explanation:
After 4 years Mary (x+4), Jack's age (x+5) + 4.
sum of the ages after 4 years :(x+4) + (x+5) +4=33
Simplifying the equation:
2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age
10 + 5 = 15 which is Jack's age.
The discount is 60% of regular price, or we can write it as

discount = 2,700/100
discount = 27
The answer is $27

Ansver:
<h2><u>
length = w + 2</u></h2><h2><u>
</u></h2><h2><u>
