Please help and try to show every bit of work that you can to help me better understand the problem, Thank You! =)
:
lets call the time spent at soup kitchen,trash pickup, and toy collecting
s, t, and c, respectively
:
c=4t...........eq 1
s=t-2..........eq 2
s+t+c=40.......eq 3
:
lets take the value of c and s in eq's 1 and 2 and plug them into eq 3
:
(t-2)+t+4t=40
:
6t=42
:
{{{highlight(t=7)}}}hours picking up trash
:
{{{highlight(c=4t=4(7)=28)}}}hours toy collecting
:
{{{highlight(s=t-2=7-2=5)}}}hours in the soup kitchen
