Question

anonymous · Answer

If you multiply 5 by 20 you get 100 then subtract that form 185 giving you 85 and divide by 5 to find the unit price of a pair of shorts which in this case is $17

s = shirts = 20

y = shorts

===========
5s +5y = 185 --- 5 shirts + 5 shorts = 185)
5(20) + 5y = 185
100 + 5y = 185
5y = 185 - 100
5y = 85
y = 85/5
y = 17

yep....each pair of shorts costs $ 17
