Question

14. Emily's meal costs $32.75 and Darren's a

meal costs $39.88. Emily treats Darren by
paying for both meals, and leaves a 14%
tip. Find the total cost.

Answer 1

She pay both meals (32.75 + 39.88) and leave a 14% tip of this value

32.75 + 39.88 = $72.63

It's 100% of the price, but she leave a 14% tip, which means that she paid 114% of the value

$72.63 ------------- 100%

$x -------------------- 114%

Multiply in cross

100.x = 72,63 . 114

100x = 8279,82

x = 8279,82

x = $82.7982

The total cost was $82.7982, the minor dolar coin is 0.01, so she left $82.80
