Bill bought 5 danishes and 9 filled donuts for $16.25 . Mary Ann bought 7 of each for $14.91. What is the price of each type of pastry?

Math, microeconomics or criminal justice
5d + 9f = 16.25
7d +7f = 14.91
35d +63f = 7(16.25)
35d + 35f = 5(14.91)
(63-35)f = 113.75 - 74.55
28f = 39.2
f = 39.2/28
f = $ 1.40 for a filled donut
7d +7f = 14.91
7d =14.91 -7(1.4)
7d = 14.91 -9.8
d = 5.11/7 = .73
d = 73 cents for danish
5d +9f = 16.25
5(.73) + 9(1.4)
= 3.65 + 12.6
= 16.25
7d +7f = 14.91
7(.73) +7(1.4)
= 5.11 +9.8
= 14.91
