Kristin spent $131 on shirts. Fancy shirts cost $28 and plain shirts cost $15. If she bought a total of 7 then how many of each
Tpy6a [65]
Hi there!!

First, Let plain shirts be x
Let fancy shirts be y 
x + y = 7
15x + 28y = 131 
Multiply first equation by 28 to eliminate y: 
28x + 28y = 196
<span>15x + 28y = 131 
</span>Subtracting the two equations:
13x = 65
<span>x = 5 </span>
Substituting x to get y:
x + y = 7
5 + y = 7
<span>y = 2 </span>
<span>Answer: 5 plain shirts and 2 fancy shirts
</span>
Hope this helps u!!
Have an amazing rest of ur day:)))

Solve 7x + 6 &lt; 3(x - 2).
sasho [114]
7x+6=3x-6
    +6       +6
7x+12=3x
-3x       -3x
 4x+12=0
-4x         -4x
 divide both sides by -4 but you have to flip the sign.   
-3>x
or  
{x | x < -3}

Sixty percent of the customers who go to Sears Auto Center for tires buy four tires and 22% buy two tires. Moreover, 14% buy few
Bezzdna [24]

Answer:

There is a 4% probability that a customer buys three tires.

Step-by-step explanation:

We have those following percentages

60% buy four tires. This is also the probability that someone buys four tires.

22% buy two tires

14% buy fewer than two tires(one or none).

P% buy three tires

The sum of the percentages must be 100%.

So

60 + 22 + 14 + P = 100

96 + P = 100

P = 4

There is a 4% probability that a customer buys three tires.
