Write an algebraic expression that models the situation “the piggy bank contained $25, and $1.50 is added each day.” use d to represent the number of days a) 25d+1.5 b) 25+1.5d c) 25d+1.5d d) 25+(1.5)(7)d

the answer is b because the piggy bank originally contained $25 and the person adds $1.50 per day.. so: 25+1.5d

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
