Answer:
Costco has the better deal.
Step-by-step explanation:
Find the unit rate for Costco:
<em>Remember, the unit rate is when one of the numbers in a ratio is 1.</em>
<em />
Toilet paper : Price
6 : 4.99
(divide both sides by 6)
1 : .83
<em>Remember to round to the nearest hundredth place because money only goes two places after the decimal point.</em>
<em />
Therefore, 1 roll of toilet paper at Costco costs 83 cents.
Find the unit rate for Target:
Toilet paper : Price
8 : 6.99
(divide both sides by 8)
1 : .87
Therefore, 1 roll of toilet paper at Target costs 87 cents.
Conclusion:
.83 < .87
In conclusion, Costco has a better deal because toilet paper is cheaper per roll.
