Maci is planning for the new school year and goes to the store to buy pens. She needs ten blue pens and 15 red pens. If a blue pen costs ten cents each and a red pen costs twice as much as the blue pen, how much money does Maci pay for the pens? Let's think step by step and output the final answer after "####".

Maci pays 10 * $0.10 = $<<10*0.10=1>>1 for the blue pens.
Each red pen costs 2*$0.10 = $<<2*0.10=0.20>>0.20
She pays 15*$0.20 = $<<15*0.20=3.00>>3.00 for the red pens.
To buy all the pens she needs, Maci pays $3+$1= $<<3+1=4>>4
