Kolo purchesed food for herslef and her friends. she bought 4 cheeseburgers for 2.25 each 3 french friues for 1.25 each and 4 drinks for 4.00 each. write and evaluate an expression to find how much the food costs

Well assuming that we denote cheeseburgers by cb. cb = 2.25 dollars so four cb would be for 9 $.

Similarly we denote french fries by ff. ff = 1.25 dollars so three ff would be for 3.75 $.

Similarly we denote drinks by d. d = 4 dollars so four d would be for 16.00 $.

So in total the expression would be 4*cb + 4*d + 3*ff which equates to 28.75$

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
