Answer:

$18

Step-by-step explanation:

we proceed by first solving for the unit cost of a sheet

then calculate the cost for any number of sheet

We are told that a builder could buy 6 sheets for the cost of $9

this means that one sheet would cost 9/6= $1.5

Now the builder buys 12 sheets

therefore the cost of 12 sheets will be

12*1.5= $18

Marcus needs to bike at least 80 mi this week for a training if he has already bike 25 mi this week then how many miles should h
Rashid [163]

Marcus needs to bike at least 11 miles each day.

Step-by-step explanation:

Given,

Distance to cover = 80 miles at least

Distance already biked = 25 miles

Number of days left = 5

Let,

x be the distance to cover in 5 days.

According to given statement;

Number of days left * Distance to cover + distance already bike ≥ Total distance to travel

5x+25\geq 80\\5x+25-25\geq 80-25\\5x\geq 55

Dividing both sides by 5

\frac{5x}{5}\geq \frac{55}{5}\\x\geq 11

Marcus needs to bike at least 11 miles each day.
