Step-by-step explanation:
Two combines are able to harvest acres of crops = 320
1 is able to harvest acres of crop = [tex]\frac{320}{2} = 160[/tex]
Three combines are able to harvest acres of crops = [tex]160 \times 3[/tex]
= [tex]480[/tex]
Four combines are able to harvest acres of crops = [tex]160 \times 4[/tex]
= [tex]640[/tex]
Six combines are able to harvest acres of crops = [tex]160 \times 6[/tex]
= [tex]960[/tex]
Seven combines are able to harvest acres of crops = [tex]160 \times 7[/tex]
= [tex]1120[/tex]
