A maintenance squad has $250$ spark plugs in their inventory. After a week of vehicle repairs, the inventory is reduced by $40\%$ . How many spark plugs are left in the inventory?

Cevap: 150 spark plugs

Cevap

150

Since

40\%

of the inventory was used,

60\%

remains. Multiplying the original

250

spark plugs by

0.60

results in

150

spark plugs left.

Adım Adım Çözüm

Calculate the percentage of the inventory that remains.

100\% - 40\% = 60\%

The total starting inventory represents

100\%

. Subtracting the

40\%

reduction gives the percentage that is left.

Calculate

60\%

of the initial

250

spark plugs.

250 \times 0.60 = 150

Multiplying the initial amount by the decimal form of the remaining percentage gives the final quantity.
