Since there are 7 backpacks that cost 8$ each , multiply 7 times 8 and you will get 56. Now since the pencils and pens cost an extra 5$ , multiply 7 by 5 to get 35.Now add 56+35=91.

Answer choice B is using the distributive property.
The equation is 3n - 5 1/2. 5 1/2 = 5.5
3n - 5.5
n could equal 1 so, 3 x 1 - 5.5 = -2.5
3n - 5 1/2 = -2.5
10 + x = 62
62: Total Amount
10: The sum of 10
X: Jenny’s savings
