Mrs doubtfire is planning to place a fence around her backyard. the fencing costs $1.95 per yard. she buys f yards of fencing and pays $3.50 in tax. if the total cost of the fencing is $81.50, write an equation to represent the situation.

a. 3.50f + 1.95= 81.50
b. 1.95f + 3.50 = 81.50
c. 1.96f - 3.50= 81.50
d. 3.50f - 1.95 = 81.50

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

is should be y = 5x

step-by-step explanation:

correct me if im wrong

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
