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.

Short answer

Total cost $=\$41.5$.

Step-by-step solution

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 diskrole="math" localid="1642079399323" $=\$3.254\times \$3.25$

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.

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