Answer:
T = 4B + 10C
Step-by-step explanation:
Since there are 4 doughnuts in a bag then there are 4B doughnuts in B bags
Since there are 10 doughnuts in a carton then there are 10C doughnuts in C cartons, thus summing the two quantities gives
T = 4B + 10C

<em>Set up a proportion.</em>
<em />
<em>75 / 125 = x/1300</em>
<em />
<em>125 10.4 = 1300</em>
<em />
<em>75 * 10.4 = 780</em>
<em />
<em>x=780</em>
B1 = 2
b2 = (b1)^2 + 1 = 2^2 + 1 = 5
b3 = (b2)^2 + 1 = 5^2 + 1 = 26
b4 = (b3)^2 + 1 = 26^2 + 1 = 676+1=<span>677</span>
X=4 and y=6
For this, you should use simultaneous equations
