Answer:
(a) 3d=81
(b) 27
Step-by-step explanation:
every day, kojo write 3 pages
number of days he has written his story= d days
therefore number of pages he has written= 3d
from the final sentence,
3d= 81
<h3>(a) the equation to describe the situation: </h3><h3>3d= 81</h3>
(b) number of days kojo has been writing his story
3d= 81
dividing through by d
3d/3= 81/3
d = 27
<h3>therefore number of days = 27</h3>
The third one because it matches plus im copy

<em>Additional comment</em>
It is helpful to memorize the squares of integers 1-20 and the cubes of integers 1-10. Being able to recognize these numbers can save you a lot of time on problems like this.
Let the amount that the boys sold be x, the amount that girls sold will be 3x. The total will be given by:
x+3x=180
4x=180
solving for x we get:
x=180/4
x=45
Thus, boys sold $45, the girls provided 45*3=$135
