You can put this solution on YOUR website! John is going to buy ties at $7.50 per tie and some shirts at $18.50 each. If he buys twice as many ties as shirts and spends no more than $205. What is the greatest number of shirts he can buy. ( taxes are included)
------
Value Inequality:: 7.5t + 18.5s <= 205 dollars
Quantity ::::::: t = 2s
----------------------
Substitute for "t" and solve for "s"::
7.5(2s) + 18.5s <= 205
-----
15s + 18.5s <= 205
33.5s <= 205
s <= 6 (# of shirts he can buy)
Solve for "t"::
t = 2s
t <= 12 (# of ties he can buy)
