There are 8 tenths in the sum. .65+.24 is .89. tenths are the first digit to the right of the decimal. 80 and 8x10=80
all you have to do is see whether both variables of each point meet both contraints:
for a) 1<3 and 2>1 is true so a is a solution to the system
100+30=130
100+40=140
online price is 130% or original
superstore price is 140% or original
the difference bewteen them is 140-130=10% of the original price
A. 1.3 times 160=208=online
1.4 times 160=224=superstore
B. difference is 224-208=16=10% of 160
it is 10% of the original price
A. online=$208
superstore=$224
B. $16, this is 10% of the original price
Answer:
The error is founded in the slope, specifically in the run.
When seen a negative slope, that only applies to the rise but <u>not</u> the run.

The slope had not mentioned any 2 in the run.
So it would sound like down 3, over 1, starting from 2.
Shade 3 boxes vertically and 5 boxes horizontally and then you have to use that to just solve the problem because the boxes represent the fractions
