To set up the system of equations for Miles and Emma's purchases, let's define the variables:
- Let \( j \) represent the cost of one jar of jam.
- Let \( p \) represent the cost of one pie.
Part 1: Write Miles' equation.
Miles buys 5 jars of jam and 2 pies for a total of $37.50. This can be expressed as:
\[ 5j + 2p = 37.50 \]
Part 2: Write Emma's equation.
Emma buys 4 jars of jam and 3 pies for a total of $40.50. This can be expressed as:
\[ 4j + 3p = 40.50 \]
Thus, the system of equations is:
- \( 5j + 2p = 37.50 \)
- \( 4j + 3p = 40.50 \)
