Engineers at Triangle Electronics use special silver wire to manufacture fuzzy logic circuit boards. The wire comes in 840-foot rolls that cost $1,200 each. Each board requires 4 feet of
wire.
a. How many circuit boards can be made from each roll?
B. What is the cost of wire per circuit board?

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

answer:   2 multiplied by x =24
