Question

Write and evaluate an expression to find the total cost of purchasing 1 collar, 2 T-shirts, 3 kerchiefs, 1 leash and 4 flying disks.

Step-by-Step Solution

Answer

Total cost $=\$41.5$.

Step 1. Given information.

Cost of 1 studded collar = $4.50

Cost of 1 kerchief = $3.00

Cost of 1 doggy T-shirt = $6.25

Cost of 1 leash = $5.50

Cost of 1 flying disk = $3.25

Step 2. Introduce the variable.

Consider the total cost of purchasing 1 collar, 2 T-shirts, 3 kerchiefs, 1 leash and 4 flying disks be x.

Step 3. Write the equation.

Cost of 1 studded collar $=1\times \$4.50$

 

Cost of 3 kerchiefs $=3\times \$3.00$

 

Cost of 2 doggy T-shirt $=2\times \$6.25$

 

Cost of 1 leash $=1\times \$5.50$

 

Cost of 4 flying disk  $=\$3.254\times \$3.25$

 

So, the equation will be:

$x=1\times 4.50+2\times 6.25+3\times 3.00+1\times 5.50+4\times 3.25$

Step 4. Solve the equation.

Take the equation $x=1\times 4.50+2\times 6.25+3\times 3.00+1\times 5.50+4\times 3.25$ and solve it.

$\begin{array}{l}x=4.50+12.50+6.00+5.50+13.00\\ x=\$41.5\end{array}$
