Angela bought 150 pins and 28 needles for sewing. The pins each weigh 0.00035 , and the needles each weigh 0.00043. What is the total weight of the pins and needles Angela bought?
First, let's calculate the total weight of the pins:
Total weight of pins = 150 pins * 0.00035 g/pin
Total weight of pins = 52.5 g
Next, let's calculate the total weight of the needles:
Total weight of needles = 28 needles * 0.00043 g/needle
Total weight of needles = 12.04 g
Now, let's find the total weight of the pins and needles:
Total weight = 52.5 g (pins) + 12.04 g (needles)
Total weight = 64.54 g
Therefore, the total weight of the pins and needles Angela bought is 64.54 grams.
