answer with an explanation.

Sum of angles of a triangle = 180°

91 + 10x - 4 + 8x +3 = 180
18x + 90 = 180
18x = 90
x = 5°

Sum of angles of a triangle = 180°

91 + 10x - 4 + 8x +3 = 180
18x + 90 = 180
18x = 90
x = 5°

Lets use the letter C to represent cats and D to represent dogs.

A)     2.35c + 5.50d = 89.50

For B, they give you numbers to plug into your equation.
c = 8
d= 14

B) 2.35(8) + 5.50(14) = 89.50
     18.80 + 77.00 = 95.80

So what Pat said is incorrect because that would mean they spent more than 89.50.

Hope this helps! :)
