25A. Students at Valencia College
earned $250 selling candles. They want to accumulate $2,000 for a club trip.
Using G to represent the percentage of their goal that has been reached,
translate this problem into an algebraic equation.
a) G (.01)(250) = 2000
b) G (.01)(2000) = 250 c) G
(.01) = (250)(2000) d) G = (.01)(250)(2000)
25B. A student buys a used book for $19.50.
This is 85 % of the original price of the book. Using B to represent the
original price of the book, translate this problem into an algebraic equation.
a) (.85)B = 19.50 b) B
= (.85)(19.50) c) (.15)B = 19.50 d) .85 = 19.50B
25C. Jill purchased a shirt from the Gap for
$45. This included 7% sales tax. Using A to represent the price of the
shirt before tax was added on, translate this problem into an algebraic
equation.
a) A – (.07)A = 45
b) (.07)A = 45 c) A + (.07)A = 45 d) A
= (.07)(45)
25D. A manufacturer of electronic components
expects 1.5% of its product to be defective. Using D to represent the
number of defective components in a batch of 28000, translate this problem into
an algebraic equation.
a) 28000D = 1.5 b)
D = (.015)(28000)
26A. The list price of a car is $12,905.
Using R as the rebate that the manufacturer is giving, translate this
problem into an algebraic expression that will give the total price of the car.
