Peter and Stacey own a farm. On market day, corn sells for $0.35 per pound and the tomatoes sell for $0.74 per pound. This year they grew 5,000 pounds of corn and 10,000 pounds of tomatoes. If they sell 90% of their crops, what is their total revenue, rounded to the nearest penny?

step-by-step explanation:

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
