Question

Hank bought 3 more boxes of cereal than gallons of milk. He bought x boxes of cereal at $2.79 each. Each gallon of milk costs $4.49. Consider the expression 2.79x + 4.49 (x - 3). Determine if each statement is True or False. True False The term x - 3 represents the number of gallons of milk. B True False The coefficient 2.79 represents the cost of one box of cereal. True False The expression represents the total number of boxes of cereal and gallons of milk

Answer 1

3 more boxes of cereal than gallons of milk

x = number of boxes of cereal

cost per box of cereal: $2.79

Cost per gallon of milk: $4.49

y= 2.79x + 4.49 (x - 3)

So, to obtain the total cost, we have to multiply the cost of each box of cereal (2.79) by the number of boxes of cereal (x) and add the product of the cost of each gallon of milk (4.49) and the number of gallons of milk (x-3)

So:

The term x - 3 represents the number of gallons of milk. TRUE

The coefficient 2.79 represents the cost of one box of cereal. TRUE

The expression represents the total number of boxes of cereal and gallons of milk​ FALSE

The expression represents the total cost.
