Enver has a $20 gift card for a smoothie shop. He calculates that if he buys a smoothie for $5.10 and a pack of almonds for $1.90, he will have $17.30 left on his card. Which best shows whether or not this is a reasonable answer, and why?

Respuesta :

$17.30 is not a reasonable answer because the smoothie and the almonds costed $7 which would leave the $20 gift card with $13 remaining.

Answer:

This is not a reasonable answer because 20 – 5 – 2 = 13.Step-by-step  

explanation:

5.10+1.90=7

20-7=13
