Explanation:

6 apples at $0.49/apple

Cost of apples purchased =  6 × $0.49 = $2.94

1 gallon of milk at $3.48/gallon

Cost of milk purchased = 1 × $3.48 = $3.48

2 loaves of bread at $1.49/loaf

Cost of bread purchased = 2 × 1.49 = $2.98

Total cost of purchase is the sum of all the individual items purchased

= $2.94 + $3.48 + $2.98

= $9.40
