Question

Victoria wants to purchase a skateboard. She has $125 to spend. She finds one that regularly sells for $139.99 and is on sale for 15% off. Sales tax is 7%. Victoria says that she has enough money to buy the skateboard. Is she correct? Explain.

Answer 1

we know that
Victoria has $125 to spend

[purchase price skateboard]=$139.99-0.15*$139.99-----> $139.99-$21
[purchase price skateboard]=$118.99

sales tax is 7%----------> 0.07*$118.99----------> $8.33
sales tax is $8.33

Victoria has to pay [$118.99]+[$8.33]=$127.32
$127.32 > $125
therefore
Victoria has not enough money to buy the skateboard

the answer is
Victoria has not enough money to buy the skateboard
