Answer:
210 candy bars
85 gum
Step-by-step explanation:
$200=0.75cb+0.50gum
cb+gum=295
gum=295-cb
substitute
$200=0.75cb+0.50(295-cb)
$200=0.75cb+147.5-0.50cb
$200=0.25cb+147.5
0.25cb=52.5
cb=210
gum=295-210=85
<span>On a certain survey it says:
12 out 15 people in the United States prefer eating at the restaurant rather
than home.
To know how many percent is this.
=> 12 / 15
=> 0.8 which is also 80%
Now, the 80% of the those people in the
survey is 400.
Find the total number of people who took
the survey.
Since we already have the 80%, we need to find the number of 20%
=> 400 x 20%
=> 400 x .20
=> 80
=> 400 + 80
=> 480 => the total number of people who took the survey
