You can make equations out of the information Let L be Lin, G be Greg, and F be Fran
L = 4 + G ---"Lin sold 4 more shirts than Greg" F = 3L ---"Fran sold 3 times as many shirts as Lin" F + G + L = 51 ---"In total the three sold 51 shirts"
Use F + G + L = 51 Substitute the equations in for F and L (because you need to know the G) like this....
(3L) + G + (4+G) = 51
You still have a variable besides G in there... you can use the L= 4+G and substitute again so that there are only G's
( 3(4+G) ) + G + (4+G) = 51 ---- SIMPLIFY :D ( 12 + 3G ) + G + 4 + G = 51 12 + 3G + G + 4 + G = 51 ---Combine like terms 16 + 5G = 51 </span>
First youll want to add 18 and 29. which gives you 43. then you’ll want to find out how much is 29 people percentage wise. so you’ll do 29/43 which gives you 67.44% if it’s answer choices. you round it to the most whole number if they don’t use decimals.
If Ken wants to pay more than 130, he needs to drive more than 90 miles. You subtract 94 from 130, which equals 36. 36 divided by .4 (for the price per mile) and it equals 90.
