Explanation:
Given
Members = 75
Cost of Shirt = $3
Color = $50 on all shirts
Required
Determine an equation to represent the scenario
Represent the members with x
Such that:
![x = 75](https://img.qammunity.org/2021/formulas/mathematics/high-school/sptdqgtj83dutgld8adaarij3aggj14b49.png)
First, we need to determine the total cost of ordering x shirts
A shirt costs $3;
So,
![x\ shirts = 3 * x](https://img.qammunity.org/2021/formulas/mathematics/high-school/gocd1f071033xka46e2k0uzopsabn9ufbf.png)
![x\ shirts = 3 x](https://img.qammunity.org/2021/formulas/mathematics/high-school/ox9b1ink9zvsm7vmnj2abjj6m1j266tvto.png)
Next, we determine the total cost of colors
Represent each color with y
![1\ color = \$50](https://img.qammunity.org/2021/formulas/mathematics/high-school/4ws3uwprx14emue2k2whz3v84z7o91lc3c.png)
![y\ color = \$50 * y](https://img.qammunity.org/2021/formulas/mathematics/high-school/glkmajuanyfn0lbv73japlzc7qvnoq4dhv.png)
![y\ color = 50 y](https://img.qammunity.org/2021/formulas/mathematics/high-school/ce36jldjch5vgz6p5u6kwejdy9muz0xg14.png)
The required equation is calculated as thus;
![Equation = x\ shirts + y\ color](https://img.qammunity.org/2021/formulas/mathematics/high-school/f351d5ahnnw4dn52j7whn2n6rt0pfvyx5b.png)
![Equation = 3x + 50y](https://img.qammunity.org/2021/formulas/mathematics/high-school/ymv57kcv7h36deh46x1l5dau216izb9pmh.png)
Substitute 75 for x
![Equation = 3 * 75 + 50y](https://img.qammunity.org/2021/formulas/mathematics/high-school/5bwglmlxx07s1k227afs7e9ywmdz6kspjy.png)
![Equation = 225 + 50y](https://img.qammunity.org/2021/formulas/mathematics/high-school/i6w0z4nrng56nid0i6jcd74upqao0zclp2.png)
