Answer:
1 hour to build a website
5 hours to update websites
Explanation:
x is the hours to build a website
y is the hours to update websites
x + y = 6 ------> 25x + 25y = 150
25x + 15y = 100
10y = 50
y = 5
25x + 15 (5) = 100
25x + 75 = 100
25x = 25
x = 1
So, LaShawn needs 1 hour to build a website and 5 hours to update websites to allow him to reach his goals.
