Solution to yesterday’s problem:
Classy Clothiers charges $10 per month with a $25 initial fee. Terrific Tailors charges $15 per month. Using t to represent time and C to represent cost, we can write the equation for Classy Clothiers as follows:
and for Terrific Tailors:
Since the problem asks for the value of t so that the two costs are equal, let’s set the equation so that the cost for Classy Clothiers equals the cost for Terrific Tailors.
To solve this equation, subtract 10t, then divide both sides by 5 to get t = 5. So the costs for both subscriptions will be the same after 5 months.
