the TV Margaret one cost $270 this week on the TV that is discounted by 25% Margaret must pay 6% sales price which saves the most money

C

Step-by-step explanation:

Method A:

270 decrease 25% =

270 × (1 - 25%) = 270 × (1 - 0.25) = 202.5

202.5 increase 6% =

202.5 × (1 + 6%) = 202.5 × (1 + 0.06) = 214.65

Method B:

270 increase 6% =

270 × (1 + 6%) = 270 × (1 + 0.06) = 286.2

286.2 decrease 25% =

286.2 × (1 - 25%) = 286.2 × (1 - 0.25) = 214.65

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

The total nom of  code that can be used is equal to 5+3 = 8

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7
