Answer:
111
Step-by-step explanation:
divide 42 by 14 and get 3 then multiply 3 by 37 and get 111
To find out the cost of 37 inches of wire at the same rate as 14 inches, we can set up a proportion. Solving for x in the proportion yields a cost of 111 cents for 37 inches of wire.
To find out how much 37 inches of wire will cost at the same rate, we can set up a proportion. We know that 14 inches of wire costs 42 cents, so we can say that the cost is directly proportional to the length. The proportion can be written as:
14 inches / 42 cents = 37 inches / x cents
To solve for x, we cross-multiply and get:
14x = 37 * 42
Dividing both sides by 14 gives us:
x = (37 * 42) / 14
Calculating this out, we find that:
x = 111 cents
Therefore, 37 inches of wire will cost 111 cents.
