SOLUTION
Given the question, the following are the solution steps to answer the question.
STEP 1: Represent the unknown terms
Let h be the number of hours
Let t be the total number of baskets filled
STEP 2: Interpret the statements by getting the required equations
For Greg
[tex]t=7+5h[/tex]For Annie,
[tex]t=13+4h[/tex]STEP 3: Calculate the time they will fill the same number of baskets
this means that t will be equal to t
[tex]\begin{gathered} t=t \\ 7+5h=13+4h \\ 7-13=4h-5h \\ -6=-h \\ h=6 \end{gathered}[/tex]time = 6 hours
STEP 4: Calculate the total number of apples they will have each picked
For Greg
[tex]\begin{gathered} t=7+5h \\ h=6 \\ t=7+5(6)=7+30=37 \end{gathered}[/tex]For Annie,
[tex]\begin{gathered} t=13+4h \\ t=13+4(6)=13+24=37 \end{gathered}[/tex]ANSWER:
Greg and Annie would have each filled 37 baskets in 6 hours
