To determine how much more money you need, we can use the information provided:
1. Define the Variables:
- Let's denote the total amount of money needed for the material and equipment as [tex]\( T \)[/tex].
- The amount of money you have fundraised as a class is [tex]\( R \)[/tex] 1200. We will denote this as [tex]\( F = 1200 \)[/tex].
2. Understand the Relationship:
- Given that the amount fundraised ([tex]\( F \)[/tex]) is 1200 less than the total amount required ([tex]\( T \)[/tex]), we represent this relationship as:
[tex]\[
F = T - 1200
\][/tex]
3. Solving for the Additional Amount Needed:
- The additional amount required is the difference between the total amount needed ([tex]\( T \)[/tex]) and the amount fundraised ([tex]\( F \)[/tex]).
- Let's call the additional amount [tex]\( A \)[/tex]. We can express this relationship as:
[tex]\[
A = T - F
\][/tex]
4. Substitute the Fundraised Amount:
- We know from the prior relationship that [tex]\( F \)[/tex] is 1200, hence:
[tex]\[
F = 1200
\][/tex]
- Substitute this into our equation for [tex]\( A \)[/tex]:
[tex]\[
A = T - 1200
\][/tex]
Thus, the additional money needed is the total amount needed ([tex]\( T \)[/tex]) minus 1200.
### Final Answer:
You need [tex]\( T - 1200 \)[/tex] more money, where [tex]\( T \)[/tex] is the total amount required for materials and equipment.
