# Ackson is at a collectibles fair. He has exactly $8 and will purchase a collectible card from a vendor for$3. What percent of his money will Jackson spend on the purchase?

color(green)(37.5%)
Let $x$ be the percentage of his $8 that Jackson spends on a card. We are told color(white)("XXX")x xx$8 = $3 After dividing both sides by $8
color(white)("XXX")x=(cancel($)3)/(cancel($)8)=37.5
