Answer : He saved $30 money.

Step-by-step explanation :

when he earned $15 from babysitting, he saved money = 6 dollars

when he earned $1 from babysitting, he saved money = $\frac{6}{15}$ dollars

when he earned $75 from babysitting, he saved money = $\frac{6}{15}\times 75=30$ dollars

Therefore, He saved $30 money.
