Answer:
the length of the thread remaining is 790 cm
Step-by-step explanation:
Given;
original length of the thread, L₀ = 10 m = 1000 cm
the length of the thread used, L₁ = 210 cm
The length of the thread remaining is calculated as follows;
ΔL = L₀ - L₁
ΔL = 1000 cm - 210 cm
ΔL = 790 cm
Therefore, the length of the thread remaining is 790 cm
One company charges:
$376 + $12*h
Other company charges:
$280 + $15*h
They will both charge the same when:
$376 + $12*h = $280 + $15*h
96 = 3*h
hours = 32
Cost will be $760
Double Check
$376 + $12 * 32 hours = $760
$280 + $15 * 32 hours = $760
Hello! The mark down is 12.5%, which means that will still have to pay a portion of the price. Mark down is a discount, where the price of the item goes down. To find the amount that needs to still be paid, subtract 12.5 from 100. 100 - 12.5 is 87.5 You still have to pay 87.5% of the price. Now, let's multiply that number by 32 to get the new price. 32 * 87.5% (0.875) is 28. There. The retail price is $28.
