Kim spent $214 on shirts. Fancy shirts cost $27 and plain shirts cost $13. If she bought a total of 10, then how many of each kind did she buy?
+188 Let's say x is the number of fancy shirts Kim bought, and y is the number of plain shirts she bought.
27x + 13y = 214
x + y = 10
This means that x = 10 - y. We can plug 10 - y into the equation 27x + 13y = 214. This gives us 27 ( 10 - y ) + 13y = 214.
Expand: 270 - 27y + 13y = 214. Isolate the variable: 27y - 13 y = 270 - 214. Simplify and divide: y = 4.
To get x, simply minus y (which is 4) from 10.
Now we know that the number of plain shirts Kim bought is 4, and the number of fancy shirts Kim bought is 6.
