If next week, she is expecting 1000 customers, about how many would you expect to pay with a debit card? Round your answer to the nearest whole number. Answer:

Calculate total customers: Calculate the total number of customers from last week. Total customers = Customers who paid cash + Customers who used a debit card + Customers who used a credit card Total customers = 28 + 15 + 61 Total customers = 104Calculate debit card proportion: Calculate the proportion of customers who used a debit card last week. Proportion of debit card users = Number of customers who used a debit card / Total number of customers Proportion of debit card users = 15 / 104Estimate debit card users: Use the proportion of debit card users to estimate the number of debit card users among the expected customers next week. Expected number of debit card users = Proportion of debit card users × Total expected customers next week Expected number of debit card users = (15 / 104) × 1000 Expected number of debit card users ≈ 144.23Round expected number: Round the expected number of debit card users to the nearest whole number. Rounded expected number of debit card users ≈ 144

Q. Tallulah owns a small business selling clothing. She knows that in the last week

28

customers paid cash,

customers, about how many would you expect to pay with a debit card? Round your answer to the nearest whole number.

Answer:

Calculate total customers: Calculate the total number of customers from last week. $\newline$ Total customers = Customers who paid cash + Customers who used a debit card + Customers who used a credit card $\newline$ Total customers = $28 + 15 + 61$ $\newline$ Total customers = $104$
Calculate debit card proportion: Calculate the proportion of customers who used a debit card last week. $\newline$ Proportion of debit card users = Number of customers who used a debit card / Total number of customers $\newline$ Proportion of debit card users = $\frac{15}{104}$
Estimate debit card users: Use the proportion of debit card users to estimate the number of debit card users among the expected customers next week. $\newline$ Expected number of debit card users = Proportion of debit card users $\times$ Total expected customers next week $\newline$ Expected number of debit card users = $(15 / 104) \times 1000$ $\newline$ Expected number of debit card users $\approx 144.23$
Round expected number: Round the expected number of debit card users to the nearest whole number. $\newline$ Rounded expected number of debit card users $\approx 144$
