The Pine Apple Store found that 25% of their weekly customers would purchase a new R- phone before leaving the store. If this was equivalent to 75 customers, how many total people entered the store last week?

from the informations given in the question;


\begin{gathered} \text{Let } \\ nu\text{mber of customers who enter the store last w}eek\text{ = x} \end{gathered}

since 25% of their weekly customers would purchase a new R- phone before leaving the store and this was equivalent to 75 customers

then we have


25\text{\% 0f x = 75}

hence we need to solve for x


\begin{gathered} 25\text{\% of x =75} \\ \text{implies} \\ (25)/(100)\text{ }*\text{ x = 75} \\ (1)/(4)\text{ }*\text{ x = 75} \\ (x)/(4)\text{ = 75 } \\ \text{cross multiply} \\ x\text{ = 4 x 75} \\ x\text{ = 300} \end{gathered}

therefore

the number of customers that enter the store last week is 300 customers
