Respuesta :
let family income be x
32%x=15680
32/100x=15680
x=15680X100/32
x=49000
I came up with 49,000 as the family's annual income.
x is the annual income
if we set the equations to 32/100 x = 15,680, we can multiply by 100, this leaves us with 32x=1568000
if we divide by 32, we're left with
x = 49,000
