Juan Ramirez sells suits in a major department store on weekends. He earns a commission of 5 percent on the first ten suits, and
Zepler [3.9K]
So, the first 10 suits came with a commission of 5%, so for each suit it was:

250*5%

this is \frac{250*5}{100} = \frac{25*5}{10} = \frac{25}{2} =12.5

but this counts for 10 suits, so together his commssion was 10*12.5=125 dollars

and the "extra" 3 suits came with a comittion of 5+3 percent, so 8 percent, which is


 
 \frac{250*8}{100} = \frac{25*8}{10} = \frac{25*4}{5} =20

for each suit, and 60 in total.

his total comission was 125+60=185 dollars.

Which equation is y = (x + 3)2 + (x + 4)2 rewritten in vertex form? mc010-1.jpg mc010-2.jpg y = 2(x + 7)2 – 73 y = (x + 7)2 – 24
MArishka [77]
Y=(x+3)²+(x+4)²
y=x²+6x+9+x²+8x+16
y=2x²+14x+25
y=2(x²+7x+3.5²-3.5²)+25
y=2(x+3.5)²-2*3.5² +25
y=2(x+3.5)²+0.5
