Kristin spent $120 on shirts. Fancy shirts cost $35 and plain shirts cost $10. If she bought a total of 7 then how many of each kind did
she buy?

2 fancy shirts

5 plain

Step-by-step explanation:

2 fancy- 70$

5plain- 50$

50+70=120

she bought 2 fancy shirts, and 5 plain shrits.

Step-by-step explanation:

$35×2=$70 (for the fancy shirts so she bought 2 fancy shirts)

Now, we have 5 shirts left that she bought so they must be plain shirts. to check, we would multiply $10×5=$50, then we would add $70(from the fancy shirts) and $50 (from the plain shirts) and get a total of $120.

I hope this helps!

it has to have an angle of 90 degrees
