Answer:
2c + 4d= 92
Explanation:
In order to get this answer, you have the values for c and d. You now plug in the numbers to replace the variable. So now, for 2c you have 2x30 and for 4d you have 4x8. You multiply because when using variables, there is no sign and when there is no sign it means to multiply. After you solve for 2x30 you should get 60 and after you solve for 4x8 you should get 32. You now add up 60+32 to get 92. Hope this helps! :)
