Fields Grocery Store buys bread from
the bread factory for $0.80 per loaf.
The store sells the bread for $2.40
per loaf. If the store sold 10 loaves
of bread on Monday, how much did
the store earn in profit on bread for
the day?
A $1.60
B $8.00
C$16.00
D $24.00

C. $16.00

Step-by-step explanation:

First, let's find how much they profit from one loaf

The profit is the difference between how much they sell it for and what they buy it for.

So, we can subtract what they buy the bread for from how much the sell it for

selling price-buying price

2.40-0.80=1.6

So, they profit $1.60 per loaf

To find how much they profit for 10 loaves, multiply their profit from one loaf by 10

profit*10

1.60*10=16

The profit for 10 loaves is $16, or choice C

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
