Answer:
80 gifts
Step-by-step explanation:
Maddison hid 12 of her sister's birthday gifts around the house. If this was 15% of the gifts, how many total gifts did her sister have?
Let the Total gifts that her sister has be represented by x
Hence:
15% of x = 12
15/100 × x = 12
15x /100 = 12
Cross Multiply
15x = 100 × 12
15x = 1200
x = 1200/15
x = 80 gifts
Hence, the total gifts her sister has is 80 gifts
