Question

Victoria wants to purchase a skateboard. She has $125 to spend. She

finds one that regularly sells for $140 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?

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
