This week, 28% of customers ordered the fish entrée. If there were 900 customers this week, how many customers ordered the fish entrée?

252 people

Step-by-step explanation:

There are two ways of solving.

you can use a proportion or an equation.

is=% as a decimal×of

or the proportion

step 1- Identity which is which.

28 is the percent and 900 is the of. we need to find the is.

step 2-

if you use an equation:

is=0.28x900

is=252

252 people ordered fish

you can also use a proportion

x is a variable in place of is.

then, we cross cancel.

25200=100x

x=252

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

it is c, trust i got your back lol
