The answer to 600,000+80,000+10 in standard form is simple. It's 680,010. Just do the addition if you don't understand how to turn a math problem into standard form
A)
y= total charges
x=number of mattresses
Company A: y=$30x+13 Company B: y=$28x+15
B)
plug x=4 into both equations to get
A: y=30(4)+13=$133
B: y=28(4)+15=$127
Company B charges less because 127<133
C)
Plug in 7 for x
A: y=30(7)+13=$223
B: y=28(7)+15=$211
A-B=223-211
=$12 Saved
