Answer:
- E=5S+2P
- P=0.5(E-5S)
Step-by-step explanation:
Cost of a bowl of salad = $5.00
Cost of a slice of pizza = $2.00
If Paolo buys S bowls of salad and P slices of pizza, then the total amount of money he spends E can be represented by the equation:
- E=5S+2P
Next, we make P the subject of the equation above.
2P=E-5S
Therefore, The quantity of pizza he buys can be represented by the equation:
- P=0.5(E-5S)
When E=$40, we are required to complete the table below.
When S=0, E=$40
From P=0.5(E-5S)
P=0.5(40-5(0))=20
When S=4, E=$40
P=0.5(40-5(4))
=0.5(40-20)
=0.5*20
=10
When P=0, E=$40
P=0.5(E-5S)
0=0.5(40-5S)
40-5S=0
5S=40
S=8
Therefore, the completed table is:
