The total cost of 8 schoolbags is Rp192.000,00. Find the total cost of 5 similar schoolbags.
-
Rp100.000,00
-
Rp120.000,00
-
Rp160.000,00
-
Rp220.000,00
Correct Answer
A. Rp120.000,00Explanation
If the total cost of 8 schoolbags is Rp192.000,00, we can find the cost of 1 schoolbag by dividing the total cost by the number of schoolbags. So, the cost of 1 schoolbag is Rp192.000,00 / 8 = Rp24.000,00. To find the cost of 5 similar schoolbags, we multiply the cost of 1 schoolbag by 5. Therefore, the total cost of 5 similar schoolbags is Rp24.000,00 * 5 = Rp120.000,00.Rate this question:
