Find a direct relationship between x and y.
x = 3t and y = 2t + 7

y = x + 7

Step-by-step explanation:

Given

x = 3t ( divide both sides by 3 )

x = t

Substitute this value into y = 2t + 7

y = 2 × x + 7 = x + 7

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%
