Cyrus is hosting a dinner to celebrate Nowruz, the Persian New Year. His groceries cost $150
before he uses a 10%-off coupon. He also
orders $60 worth of flowers. Sales tax on the
flowers is 6.25%. What is the total amount
Cyrus spends?

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!

the answer for the second equation is (4,0)
