Question

PLS HELP!!

Cruz had d $10 bills and 4 fewer $20 bills than he has $10 bills. Enter an algebraic expression to represent how much money Cruz has in dollars. Simplify the expression, if possible.

Answer 1

Answer:Here's the basic equation

m(d) = 10d + 20(d - 2) (the money total is the 10 dollar bills plus the 20 dollar bills (which are two less than the 10 dollars))

Explanation:

To simplify it, start by distributing the 20:

m(d) = 10d + 20d - 40

add like terms

m(d) = 30d - 40
