Question

Anna can buy 12 muffins for $4.80 or 6 muffins for $2.70. Which is the better deal? Explain using unit rates.

a) 12 muffins for $4.80
b) 6 muffins for $2.70
c) Both deals are the same
d) It cannot be determined

Answer 1

By calculating the unit rates, we find that the first option, 12 muffins for $4.80, is a better deal at $0.40 per muffin, compared to $0.45 per muffin for the second option of 6 muffins for $2.70.

Step-by-step explanation:

To determine which muffin deal is better, we calculate the unit rates for both options. The unit rate is the cost per single muffin.

1. For the 12 muffins at $4.80, divide $4.80 by 12 to calculate the unit price: $4.80 / 12 muffins = $0.40 per muffin.
2. For the 6 muffins at $2.70, divide $2.70 by 6 to find the unit price: $2.70 / 6 muffins = $0.45 per muffin.

Comparing these unit rates shows that the first option, 12 muffins for $4.80, is the better deal since the cost per muffin is lower at $0.40 compared to $0.45 in the second option.
