To find the number of teaspoons of raisins per bar in 1 batch, we need to first calculate the total number of teaspoons of raisins used in 1 batch, and then divide that by the total number of bars in 1 batch.
The recipe calls for 2 cups of raisins per batch of dough, and 1 cup is equal to 48 teaspoons. Therefore, 2 cups of raisins is equal to:
2 cups * 48 teaspoons/cup = 96 teaspoons
One batch of dough makes 5 dozen bars, or 5 x 12 = 60 bars.
So, the number of teaspoons of raisins per bar in 1 batch is:
96 teaspoons / 60 bars = 1.6 teaspoons/bar
Therefore, the correct calculation to use is:
96 teaspoons / 60 bars = 1.6 teaspoons/bar
