Q2
Saving is the money left when you subtract all the expenses incurred when buying the product. In the question 2 above, the answer that best fits explains saving is, "calculate the total cost of the items at their sale price and subtract the original cost".
Q3
When buying one bread twice = 2 × $4.99 = $9.98
When two breads at once = $6.50
Saving = $9.98 - $6.50
= $3.48
Q4
Total cost = (2×2.48) + (3×1.49) + (5×0.58)
= 4.96 + 4.47 +2.90
= $12.33
The correct answers are:
calculate the total cost of the items at their sale price and subtract the original cost ; $3.48; and $12.33.
Explanation:
In order to figure out how much you've saved, you must know how much the original price would have been. You also need to know the total amount you spent on the sale items. Subtract these and you get the amount you've saved.
Buying 2 loaves of bread at $4.99 each would be $9.98. Instead, you're buying them for $6.50; this is a savings of $9.98-$6.50 = $3.48.
2 gallons of milk at $2.48/gallon comes to 2*2.48 = $4.96. 3 gallons of ice cream at $1.49 per gallon comes to 3*1.49 = $4.47. 5 pounds of strawberries at $0.58/lb comes to 5*0.58 = $2.90.
