Answer:
31%
Step-by-step explanation:
money he saved: $66
money he spent: $30
the total of his money: $66 + $30 = $96
he spent [tex]\frac{30}{96}[/tex] of his money ($30 out of a total of $96), this is equal to:
[tex]\frac{30}{96}=0.3125[/tex], which in porcentage is: [tex]31.25%[/tex]%
rounding to the nearest whole percent: [tex]31%[/tex]%
