The manufacturer of a granola bar spends $1.20 to make each bar and sells them for $2. The manufacturer also has fixed costs each month of $8,000.

10,000 bars per month is the break even number

Step-by-step explanation:

$2 - $1.20 = $0.80

The manufacturer has a profit of $0.80 per bar.

$8000/$0.80 = 10,000

He needs to sell 10,000 bars per month just to cover his costs.

For every bar he sells beyond 10,000, he's make $0.80 profit.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
