The dinner check was $58.00. If Fay gave the waiter a 20% tip, how much did she spend in all?

$69.60

Explanation:

20% is #20/100#

"of means multiply" so 20% of $58.00 means

#20/100*$58.00 = $11.60# (this is the tip)

So altogether she spent $58.00 + $11.60 = $69.60

#$69.60#

Explanation:

#20% xx $58.00 = $11.6#

#$58.00 + $11.6 = $69.60 #

It is easier to multiply #100%+20%# i.e. # 1.2# by the cost of her meal :
#1.2 xx $58.00 = $69.60 #
