Respuesta :
[tex]161 + 39 = 200 \\ 200 \div 4 = 50[/tex]
so she used 4 rolls of pennies
161 divides by 50 = 3 11/50
3 11/50 + 39/50 = 4
She used 3 11/50 roles for her son and kept 39/50 for her self out of 4 roles
3 11/50 + 39/50 = 4
She used 3 11/50 roles for her son and kept 39/50 for her self out of 4 roles
