Answer 1

Answer:

a, 1.12m

b, P 1257.75

Step-by-step explanation:

A,

9.8m × 4/5 = 7.84m

7.84m ÷ 7 = 1.12m

B,

7 × 178.25 = P1247.75

Answer 2

We are required to find how much cloth she used for each blouse

cloth used for each blouse is 1.12 meters and total cost of 7 blouses is P 1247.75

Total quantity of geena satin bought = 9.8 meters

Quantity damaged by rat = 1/5 of 9.8 meters

= 0.2 × 9.8

= 1.96 meters

Total cloth used for 7 blouse = Total quantity of geena satin bought - Quantity damaged by rat

= 9.8 meters - 1.96 meters

= 7.84 meters

Cloth used for each blouse = Total cloth used for 7 blouse / 7

= 7.84 / 7

= 1.12 meters

Cost of each blouse = P 178.25

Total cost of 7 blouses = P 178.25 × 7

= P 1247.75

Therefore, cloth used for each blouse is 1.12 meters and total cost of 7 blouses is P 1247.75
