The amount of interest earned on a savings account varies directly with the amount of money saved. If $126 in interest is earned on $3000 of savings , how much interest will be earned on $5000 of savings over time

Respuesta :

126 / 3000 = x / 5000
cross multiply
(3000)(x) = (126)(5000)
3000x = 630000
x = 630000/3000
x = 210 <===
