2) work out the oldest age that lee can be. give your answer as a whole number of years

Answer 1

Answer:

y + (y-8) < 41

lee <24 in whole numbers

Step-by-step explanation:

lee =y

toby =  lee -8

         = y-8

sum of their ages  < 41

lee + toby < 41

y + (y-8) < 41

combine like terms

2y-8 <41

add 8 to each side

2y < 49

divide by 2

y < 49/2

y < 24.5

y <24 in whole numbers
