excelhub:thankyouzanen:someone help with me my hw pls Andy sold thrice as many $5 T-shirts as $10 T-shirts. He also sold twice as many $10 T-shirts as $20 T-shirts. He collected $160 more from selling $5 T-shirts than from selling $20 T-shirts.
every $15 (3* $5), he will have $10 (1*$10)
every $20 (2 * $10 ), he will sell $20 (1*$20).
hence,
every 1 set : 6 ($5), he will have 2 ($10) & 1 ($20).
total, $160/10, 16 sets.
