A ride-share driver completed 6 trips and was paid a flat fee of $90, not including any tips. At this rate, how many trips must he complete to be paid a total of $225?

15

Step-by-step explanation:

Because 90x2.5=225 so then you do 6x2.5 and that is 15.

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
