d. 1 box: $0.97 os $0.97
0.98 > 0.97 > 0.96 > 0.95 > 0.93
Answer:
3rd answer choice: 3 for $2.79
Step-by-step explanation:
“You bought 4 boxes of facial tissues for $3.79.Which is a better buy than the one you bought?”
First, find the individual box cost for the given amount in the question. Divide the total cost ($3.79) with the amount of boxes (4) to get the individual amount:
$3.79/4 = ~0.9475, or $0.95
The first answer choice looks like 6 boxes for $5.75. Divide 6 from $5.75:
$5.75/6 = ~0.9583, or $0.96 (1 cent more)
The second answer choice looks like 2 boxes for $1.96. Divide 2 from $1.96:
$1.96/2 = 0.98, or $0.98 (3 cent more)
The third answer choice looks like 3 boxes for $2.79. Divide 3 from $2.79:
$2.79/3 = 0.93, or $0.93 (2 cents less).
The fourth answer choice looks like 1 for $0.97.
$0.97 (2 cents more)

In this case, the cheapest one by individual costs is the 3rd answer choice, as it is the cheapest by individual boxes.
