Express 0.31 as a fraction and express 0.2 as a fraction
If the one for $175 is 10% off, that means Fiana pays 90% of the price
175 * 0.9 = $157.50
It is too expensive because 157.50 is more than the 150 Fiana has.
The second bike for $225 is 35% off which means Fiana pays 65% of the price.
225 * 0.65 = $146.25
She CAN afford the bike for $225
5. A
6. No, 1/5(25x+15)-7x= -2x+3
-2(x-5)= -2x+10
-2x+3 is not equal to -2x+10
For this case, the first thing we must do is define a variable.
We have then:
p: rate in miles per hour for the last 1.5 hours
We now write the equation that models the problem.
We have then:

Rewriting we have:

From here, we clear the value of p.
We have then:
Answer:
DeAngelo's rate for the last 1.5 hours of his run is 7 miles per hour.
