If it’s only 7 ppl you would have to double the amount of people meaning that 14 people shook each other’s hands but not quite cause they shook each other’s hands 7•14=98/4=25

A new price of an item is $39.32. The percent increase was 16%. What was the original price?

Fiesta28 [93]

Answer:

let x =the original price

then 116x/100=$39.32

116x=100×39.32

116x=3932

divide both sides by 116

116x/116=3932/116

x=33.89655

(2dp)

x=33.90
