Question

information about a shipment of mirrors to a local store is shown. of all of the medium mirrors that were shipped, how many of them were broken? broken not broken total small 4 102 medium 96 large 6 214 total 402 480 68 78 164 208

Explanation:

1. First, find the total number of medium - sized mirrors:

• The total number of mirrors is 480, and the number of small mirrors is 102 and large mirrors is 214. So the number of medium - sized mirrors is \(480-(102 + 214)=480 - 316=164\).
• We know the number of non - broken medium - sized mirrors is 96.

1. Then, find the number of broken medium - sized mirrors:

• Let the number of broken medium - sized mirrors be \(x\). We know that the total number of medium - sized mirrors is the sum of broken and non - broken medium - sized mirrors. So \(x+96 = 164\), which means \(x=164 - 96=68\).

Answer:

68
