Final answer:
Mina will receive $13.33 in dollars.
Step-by-step explanation:
To calculate how much Mina will receive in dollars, we need to multiply the amount of pounds GBP she wants to exchange by the current exchange rate of 1.35 pounds GBP to $1.00 USD.
So, she will receive 18 pounds GBP * (1.00 USD / 1.35 pounds GBP) = $13.33 USD.
Therefore, Mina will receive $13.33 in dollars.
