Question 1005469
you can make equations that are equivalent and solve for x. using that x you can solve for the total amount of money.

19 + 14x = 51 + 6x
           
solve for x

minus 19 on the left

minus 6x on the right

14x - 6x = 51 - 19

8x = 31
8x = 31
x = 3.875
round up.

4 days.

check your work by plugging in 4 for x in the previous equation.

19 + 14(4) = 51 + 6(4)

75 = 75

this also gives you the amount Marshall had to pay.

money spent = 75
