Answer: 65.71%
Explanation: Share of wallet is a percentage of expenditure a consumer makes on a kind of purchase that goes to a specific company. Unlike the literal wallet, which is the $2,200 the customer earns per month, this focuses on a product category, and how much of that goes to a particular company.
In this case the product category is groceries which a customer spends $350 on per month. The portion that goes to a particular company, which is the share of wallet for that specific product category, is $230 which goes to Ubuyrite. Ubuyrite's share can be calculated as follows:
Portion of the product category going to Ubuyrite = $230
Total portion spent on the product category = $350
∴
× 100
= 65,71%
