Answer:
c + 2d = $7.00
2c + 3d = $12.00
Step-by-step explanation:
Hello!
<u>Let:</u>
- c = # of coffees
- d = # of donuts
1 coffee and 2 donuts cost $7.00
This can be repesented by 1c + 2d = $7.00, or c + 2d = $7.00
2 coffees and 3 donuts cost $12.00
This can be represented by 2c + 3d = $12.00
<u>So, the system is :</u>
c + 2d = $7.00
2c + 3d = $12.00
