Tyshawn was using guess and check to try to find the solution to an equation. He correctly found that x = 2, x = 3, x = 4, and x = 5 all made the equation he was trying to solve true before he stopped guessing values. What does this mean about the number of solutions to the equation he was trying to solve? How do you know?

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
