Kristin spent $131 on shirts. Fancy shirts cost $28 and plain shirts cost $15. She bought seven total shirts. How many fancy and

kykrilka [37]

Kristin bought 2 fancy shirts and 5 plain shirts.

Step-by-step explanation:

Amount spent on shirts = $131

Cost of one fancy shirt = $28

Cost of one plain shirt = $15

Shirts bought = 7

Let,

x be the number of fancy shirts bought

y be the number of plain shirts bought

According to given statement;

x+y=7 Eqn 1

28x+15y=131 Eqn 2

From Eqn 1

$x=7-y$

Putting this value of x in Eqn 2

$28(7-y)+15y=131\\196-28y+15y=131\\-13y=131-196\\-13y=-65$

Dividing both sides by -13

$\frac{-13y}{-13}=\frac{-65}{-13}\\y=5$

Putting y=5 in Eqn 1

$x+5=7\\x=7-5\\x=2$

Kristin bought 2 fancy shirts and 5 plain shirts.
