Final answer:
To determine how much Tina raised, we set up an equation based on the given information: the total amount raised and how much more Joanne raised than Tina. Solving the equation, we find that Tina raised $211.
Step-by-step explanation:
To solve the problem, we set up an equation based on the information given:
- Joanne and Tina together raised $577.
- Joanne raised $155 more than Tina.
- Tina raised $p.
So the equation that represents the relationship between the amounts raised by Joanne and Tina is:
J + T = $577
Since Joanne raised $155 more than Tina, we can say:
J = T + $155
Now substitute Tina's amount, $p, into this equation:
J = p + $155
We know that the total amount they raised together is $577, which is the sum of Joanne's amount and Tina's amount. This gives us:
(p + $155) + p = $577
Combining the terms and solving for $p gives us:
2p + $155 = $577
2p = $577 - $155
2p = $422
p = $211
Therefore, Tina raised $211.
