### Instruction:
 Lily had $55 in her account. She spent $7 on a shirt. She then went to another shop and spent thrice as much as she spent on a shirt. How much money is left in Lily's account?


### Response:
 Lily spent 7 * 3 = <<7*3=21>>21 dollars on the other store.
Her total spendings was 21 + 7 = <<21+7=28>>28 dollars.
So, She only has 55 - 28 = <<55-28=27>>27 dollars left on her account.
