How do I solve this word problem? (7.5% rate with 15% off)
Lotta Cash received a $50 gift card for graduation. She went shopping at the Cheap Shoppe. She bought 2 pairs of shorts at $7.99 each, 3 pairs of flip-flop sandals at $4.50 each, a bottle of suntan lotion at $8.25, a sun hat of $9.89, and 2 bottles of water at $.75 each. She got 15% off for using a gift card instead of a credit card. How much does she have left on her gift card if the tax rate was 7.5%?

Explanation:
Ignoring all the discounts and the tax rates, she is going to spend
Now she is going to get a 15% discount:
However, the tax rate was 7.5%. So she has to pay:
So now, if we minus this value from the original $50 in her gift card, we get:
Hope that makes sense!
