Pedro has a budget of $50 to spend on his mom for her birthday. He bought her a necklace for $21. He also wants to buy her new scarves that are on sale for $3 each. What is the most number of scarves he can buy her for her birthday?

9 scarfs

Step-by-step explanation:

9 scarves

Step-by-step explanation:

50 - 21 = 29

29/3 = 9 R2

So that is 9 scarves because you can't buy a fraction off a scarf

45

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
