She can buy 2 bottles of soda.

Money with Rita #=$.25#
The cost of one pizza #=$.14.49#
The cost of delivery #=$.5#
The cost of soda #=$1.99#

Amount Rita can use to buy soda = Total amount #-#[ cost of one pizza + delivery cost]

#=25 -[14.49+5]#

#=25 -19.49=5.51#

Number of soda Rita can buy #=# Amount Rita can use to buy soda #-:# cost of soda

#=5.51-: 1.99=2.77#

She can buy 2 bottles of soda.

She can buy 2 bottles of soda.

Cost of pizza plus cost of delivery and tip.

Add all amounts except for the cost of delivery and the tip.

#$14.49 + $5.00 = $19.49#

Amount left over for soda.

Subtract #$19.49# from #$25.00#.

#$25.00 - $19.49 = $5.00#

Number of bottles of soda she can buy.

Divide the amount left over for soda by the cost of the soda.

#($5.00)/($1.99) = $2.51#

Since she can only buy a whole bottle of soda, she can buy #2# bottles of soda.
