Answer
Explanation:
Step1: Calculate total pieces sold last week
$6 + 14+5 + 24=49$
Step2: Find the proportion of key - chains
The proportion of key - chains sold last week is $\frac{14}{49}=\frac{2}{7}$
Step3: Calculate the expected number of key - chains
Multiply the proportion by the number of pieces to be sold next. $\frac{2}{7}\times91 = 26$
Answer:
26
