Answer 1

Answer:

Small bag = £5.4

Medium bag = £5.7

Step-by-step explanation:

For Small Bags

First find out how many small bags make 3kg

3kg = 3000g

3000/250 = 12

Therefore 12 small bags weigh 3kg

Next find the cost of 12 small bags

12 x 0.45 = £5.4

Therefore costs £5.4 for 3kg worth of small bags

For Medium Bags

First find how many medium bags make 3kg

3kg = 3000g

3000/500 = 6

Therefore 6 medium bags weigh 3kg

Next find the cost of 6 medium bags

6 x 0.95 = £5.7

Therefore costs £5.7 for 3kg worth of medium bags
