Not knowing what you want, I'll arbitrarily choose to focus on the word problem:
Find the total cost of the blazers and pants, including the tax.
2 blazers @ $49.95 each comes to $99.90.
3 pair pants @ $17.50 each comes to $52.50.
Add these two products together: $99.90 + $52.50 = $152.40
Now mult. this result by 0.055 to find the sales tax: 0.055($152.400) =
$8.38
Finally, add together the purchase cost total and the sales tax:
$152.40 = $8.38 = $160.78 (answer)
You actually posted 3 problems, but not the instructions for the last two of them. That's why I focused on the word problem alone.
