At Home Depot, Johnny bought 3 rose bushes and 7 flats of petunias for a total of 114.75. Rosie bought 2 rose bushes and 6 flats of petunias for a total of 89.50. How much does a rose bush cost? How much does a flat of petunias cost?

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.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
