At Ralph’s fruit stand ½ pound of grapes cost 90 cents. You want to buy 5 pounds of grapes.How much will they cost? Explain what you would need to do in order to solve this problem. (OMG please hurry)

-26n -22= n - 90

-26 times a number: -26n

minus 22: -22

equal: =

90 less than a number: n - 90

Solving the Equation:

Move n to the left side of the equal sign (which becomes -n) in order to combine like terms:

-26n-n-22= -90

Move -22 to the right side of the equal sign which becomes +22

-26n-n=-90+22

solve both sides; -26n-n= -27n and -90+ 22= -78

-27n=-78

n= 2.888888
