Answer:
185
Step-by-step explanation:
We follow the order of operations.
Multiplications are done before additions from left to right in the order they appear. The operations in bold in each line are the ones being done next.
2(-20)+3[5/4(-20)]+5[2/5(50)]+4(50) =
= -40 + 3(-25) + 5(20) + 200
= -40 + (-75) + 100 + 200
= -115 + 100 + 200
= -15 + 200
= 185
