Respuesta :

Step-by-step explanation:

• C. P = Cost Price.. , S. P (Sell Price) ,

→ C.P = 100×S.P/100+Profit (when profit)

(a) C.P = 100 × 55/100 + 10 = 5500/110

C.P » $ 50

(b) C.P = 100 × 558/100+24 = 55800/124

C.P » $ 450

→ C. P = 100 × S.P/100 - loss (when loss)

(c) C. P = 100 × 680 / 100 - 15 = 68000/85

C. P » $ 800

(d) C. P = 100 × 11.78 / 100 - 5 = 1178/95

C. P » $ 12.4
