Final answer:
Amanda does not have enough money to buy 8 gallons of paint, but she does have enough money to buy 2 pints of paint thinner.
Step-by-step explanation:
Let's calculate the cost of buying 8 gallons of paint first. If Amanda buys 8 gallons of paint and each gallon costs $20, then the total cost of paint is 8 x $20 = $160. Since Amanda only has $150, she does not have enough money to buy the 8 gallons of paint.
Now let's calculate the cost of buying 2 pints of paint thinner. If each pint of paint thinner costs $10, then the total cost of the 2 pints is 2 x $10 = $20. Since $20 is less than $150, Amanda does have enough money left to buy 2 pints of paint thinner.
Therefore, Amanda does not have enough money to buy 8 gallons of paint, but she does have enough money to buy 2 pints of paint thinner.
