Work Step by Step

Mr. Washington has to buy a gallon of milk and as many boxes of cereal for $20$ dollars or less. A gallon of milk costs $3.99$ dollars and each box of cereal is $4.39$ dollars each. If we translate this into an inequality, where the amount of boxes of cereal he buys is $x$, we get this. $(3.99 + 4.39)x \leq 20$
