### Instruction:
Michael loves to paint and sells his creations. He charges $100 for a large painting and $80 for a small painting. At his last art show, he sold 5 large paintings and 8 small paintings. How much did he earn in all?

### Response:
 รายได้จากภาพวาดขนาดใหญ่คือ 100 x 5 = 500 เหรียญ
รายได้จากภาพวาดขนาดเล็กคือ 80 x 8 = 640 เหรียญ
ดังนั้น ไมเคิลได้รายได้รวมทั้งหมด 500 + 640 = 1140 เหรียญ
