Michael has $50. He wants to surprise his mom on Mother's day by buying a cake for $20, a bouquet for $36, and a set of balloons for $5. How much more money does Michael need to buy all those?
Michael will spend $20 + $36 + $5 = $<<20+36+5=61>>61.
So, he needs $61 - $50 = $<<61-50=11>>11 more to buy all those for his mom.
