Answer:
$13.60
Step-by-step explanation:
First let's find how much Gerry spends on lunch in 2 weeks (assuming she goes to school 5 days a week):
$1.25*10=$12.50
Now we find out how much she pays for the extra snack. Since in 2 weeks there are 2 Fridays then:
0.55*2=$1.10
Then we add these two together to get:
$12.50+$1.10=$13.60
Answer:
In general, when y = f(x), you are substituting a permissible x value into function f & its calculated 'output' is the value for y. Then (x,y) is an ordered pair, i.e. coordinates of a point on the graph. ... So our ordered pair is (-14,11).
Answer:
30 years old
Step-by-step explanation:
Joe's age can be set to x. Since Billy is twice as old as Joe, his age can be set to 2x. They add up to 45. You can set up an equation, 2x+x=45.
Simplify the equation.
3x=45, x=15
Joe is 15. Billy is 2(15)=30.
