dylan bought 3 identical shirts online for a total cost of $71.83 including a flat rate of $7.99 for shipping. drag numbers to complete an equation to find the cost of each shirt, s. each number may be used only once.
Answer
Explanation:
Step1: Subtract shipping cost from total cost
Let the cost of 3 shirts be $x$. The total cost is $71.83$ and the shipping cost is $7.99$. So $x=71.83 - 7.99$. $x = 71.83-7.99=63.84$
Step2: Find cost of each shirt
If 3 shirts cost $x = 63.84$, and the cost of each shirt is $s$, then $3s=63.84$. So $s=\frac{63.84}{3}$. $s=\frac{63.84}{3}=21.28$ The equation is $3s+7.99 = 71.83$.
Answer:
$3s+7.99 = 71.83$
