Question

Sally ordered some pizzas to be delivered the bill for the pizza was m dollars sally tipped the deliverer 15% of the bill

Write an expression for the total amount of money sally paid

Answer 1

A) 1.15m dollars

B)
`(x)/(30)` = 15%/100% (cross multiply)

`(100x)/(100) =(450)/(100)`

x=$4.40

$30.00+4.50

=S34.50

These are correct answers because I using Math in Focus Singapore Math by Marshall Cavendish (Grade 7). The back page has answers about your question. :)

Answer 2

The expression would be: m + 0.15m and to know how much she paid I believe it would be 26.09 (rounded)

Hope it helped!
