Answer:
The expression representing Number of the necklaces after h hours is .
Step-by-step explanation:
Given:
Number of necklaces in the beginning = 20
Number of necklaces made per hour = 4
Number of necklaces to be made = 50
We need to write the expression that represents the number of necklaces we have after h hours.
Solution:
Let the number of hours be denoted by 'h'.
now we can say that;
Number of the necklaces after h hours can be calculated by Number of necklaces in the beginning plus Number of necklaces made per hour multiplied by number of hours.
framing in equation form we get;
Number of the necklaces after h hours =
Hence The expression representing Number of the necklaces after h hours is .
