T-Shirts and ShortsDate: 8/24/96 at 19:28:24 From: Anonymous Subject: How many of each were sold? I need an equation for this problem: In the evening, a sporting goods store sells twice as many T-shirts as shorts. T-shirts are $9 dollars each, and shorts are $14 each. The total amount of money taken in for both items was $256. Find the number of each that was sold. The answer is 16 T-shirts and 8 pairs of shorts. Thanks, Dustin Date: 8/25/96 at 15:15:32 From: Doctor Robert Subject: Re: How many of each were sold? Let x be the number of shorts sold. Then 2x must be the number of T-shirts sold. Now calculate the total amount of money gathered. 14x + 9(2x) = 256 It's quite simple if you just name your variable, write expressions in terms of the variable and then write an equation from the information given. -Doctor Robert, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
