# The French club is sponsoring a bake sale. If its goal is to raise at least $140, how many pastries must it sell at S3.50 each to meet that goal? ##### 1 Answer Mar 7, 2018 43 #### Explanation: Using ratio but in fractional format We need to determine the count of pastries so we put that as the top number. Let the unknown count of pastries be $x$("count of pastries")/("cost") -> 1/($3.50)-=x/($140) Multiply both sides by$140

(1xx$140)/($3.50)=x

The units of measurement (dollars) cancel out giving

$\frac{140}{3.30} = x$

$x = 42.4242 \overline{42} \text{ }$ the bar over the digits 42 means they $\textcolor{w h i t e}{\text{dddddddddddddd}}$repeat for ever.

It is not usual to sell part of a pastry so the count is 43
