Mrs. nelson is buying folding chairs that are on sale for $10. if she has $50, which inequality can be solved to show the number of chairs c she can buy? a.) 10c≤50 b.) 10c≥50 c.) 10c> 50 d.) 10c< 50

A.) 10c≤50

Step-by-step explanation:

Hi, to answer this question we have to write an inequality using the information given:

So, if the number of chairs is "c", we can multiply "c" by $10 to obtain the cost of buying "c" number of chairs.

She only has $50, so, the cost of the chairs must be less or equal to 50.

Mathematically speaking:

10c≤50  (option A)

Feel free to ask for more if needed or if you did not understand something.  

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

answer: 1 + 1 = 11
