Answer:
23 pints of jam
Step-by-step explanation:
The expression for the number of pints of jam Oliver makes this year is 4p-9
where "p" stands for the number of pints of jam he made last year.
From the question Oliver made 8 pints of jam last year.
to find the amount of pints made this year, just substitute the value of p into the expression 4p-9.
Number of pints of jam made this year = 4p-9
= (4*8)-9
=23
