Answer:
94 pizzas will be sold
Step-by-step explanation:
We have to use the equation and replace 15 with x.
x=15
y=3.4x + 43
y=3.4(15) + 43
y=51 + 43
y=94
(15,94)
There will be 94 pizzas sold nightly if 15 coupons were issued.
Answer:
It will take 9 years
Step-by-step explanation:
Let x = number of years
you're adding x to each age to get
Pams age after x years: 14+x
Dad's age after x years: 37+x
Since the question is "In how many years will pans dad be twice as old as she will be?", this means that the equation is then
2(14+x)=37+x
Now solve for x
2(14+x)=37+x
28+2x=37+x
2x=37+x-28
2x-x=37-28
x=37-28
x=9
So the solution is x=9
This means that it will take 9 years.
