What is the value of

x

?

Calculate total rolls needed: First, we need to divide the total amount of tape needed by the amount of tape on each roll. $\newline$ So, we do $8,000 \, \text{cm} \div 2,000 \, \text{cm}.$
Divide total amount by roll amount: After doing the division, we get $4$ . So, the electrician needs $4$ rolls of tape.
