Part A) Option C/ 210 parts

Part B) Option B. 15 minutes

Step-by-step explanation:

Part A) we know that

•Each cutting machine cuts 105 parts every 3 minutes

so

6 cutting machine cuts (105*6=630) parts every 3 minutes

using proportion

Part B) we know that

Each stamping machine stamps 24 parts every 20 seconds

so

4 stamping machine stamps (24*4=96) parts every 20 seconds

using proportion

Convert to minutes

2x + 8
