The cost of y (in dollors) to spans an evening bowling is proportional to the number of games x that are bowled. it costs $17.50 to bowl 5 games. write an equation that represents the proportional relationship. and how much dose it cost to play 7 games?

5x = $17.50

$24.50

Step-by-step explanation:

for 5 games it cost $17.50

x = games

5x = $17.50

then you have to figure out how much each game costs

so you take 17.50 / 5 = 3.50

so its $3.50 a game

now to find how much 7 games would cost you have to multiply

you take 7 x 3.50 = 24.50

so it costs $24.50 to play 7 games

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
