We have
3/5=(a+5)/25
3/5=(5/5)*(3/5)=15/25
therefore
15/25=(a+5)/25
15=a+5------------------------ > a=10

the answer is the option a = 10

What does 45 - 4x equal

xxTIMURxx [149]

Let y = 0 to find the x-intercept(s).

0 = 45 − 4x

*Then subtract 45 from both sides*
-45 = -4x

*Next, DIVIDE both sides by -4*

-45
—— = x
-4

*NEXT, realize that TWO NEGATIVES MAKE A POSITIVE *

45. 4
——— = x {FLIP} x=——-
4. 45.

y-Intercept

Let x = 0 to find the y-intercept(s).

y = 45 −4(0)

NEXT, SIMPLIFY:

y=45

Answer:

The shop can cut the cost of production per sandwich to $3.75. The revenue function would then be defined as R(x)=9x.

Step-by-step explanation:

We want to make as big profit as possible by making as little sandwiches as possible. This means that we want the profit, which is $revenue- production\: cost$ to be as big as possible.

For the first choice the profit per sandwich is $8.25-4=4.25$ dollars.

For the second choice the profit per sandwich is $9-3.75=5.25$ dollars.

For the third choice the profit per sandwich is $8.5-3.5=5$ dollars.

We see here that for the second choice the profit is greatest, therefore this choice is most suitably correct.
