Sabrina spent half of her allowance going to the movies .She mowed the lawn and earned 10 dollars. What is her weekly allowance if she ended 15 dollars

allowance = 10

Step-by-step explanation:

15 = a - (a/2) + 10

2(5) = a - (a/2)2

10 = a

check:

15 = 10 - (10/2) + 10

15 = 10 - 5 + 10

15 = 5 + 10

15 = 15

the answer is simply just 6n add the two together as they have an n
