Ofelia joined a saving challenge wherein she has to save twice the amount she saved from the previous month. In January, she saved $10. How much is she going to save in May?
Ofelia saves $10 x 2 = $<T>multiply(10, 2)=20 in February.
She will save $20x 2 = $<T>multiply(20, 2)=40 in March.
She will save $40 x 2 = $<T>multiply(40, 2)=80 in April.
Thus, she will save $80 x 2 = $<T>multiply(80, 2)=160 in May.
