Answer:
132
Explanation:
let the number of sweets be 'x'
amy has 7x and bob gas 4x
now, the equation can be written as: 7x - 36 = 4x
7x - 36 = 4x
7x - 4x = 36
3x = 36
x = 36/3 = 12
so, no. of sweets amy has = 7x = 7*12 = 84
no. of sweets bob has = 4x = 4*12 = 48
therefore, no. of sweets in total = 84 + 48 = 132
