While at a beach, Daniel buys lunch for his family from a food stand. He purchases one hot dog for $2.50 and 3 hamburgers. If he spent $13 total, write and solve an equation to find h, the amount each hamburger cost

h= $3.50       ($13-$2.50)/3 = h

Step-by-step explanation:

$13 total. He spends $2.50 on a hotdog which leaves him at $10.50. He buys 3 hamburgers so $10.50/ 3 = $3.50

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
