1) A = (14)(24.5)-7^2
= 294m^2
2) A = (6)(7)+(17)(11)/2
= 135.5in^2
3) A = (8)(8)+(8)(4)/2
= 80cm^2
4) A = (7.5)(10)+(7.5)(5)/2
= 93.75cm^2
5) A = (18)(14)-9^2
= 171in^2
To find how much each pound of beans costs (assuming no tax), we get 19.75/2.5 (as we want to figure out how much 2.5 goes into 19.75) to get 7.90 as our cost per pound
Do x divided by b on both sides and then add a on both sides. :)
