Answer:
In 4 months Wyatt offer an equal number of sandwiches and tacos.
Step-by-step explanation:
We are given the following in the question:
Types of sandwiches = 8
Rate of increase of sandwich = 1 per month
Thus, number of sandwiches in x months will be given by
Types of tacos = 4
Rate of increase of tacos sandwich = 2 per month
Thus, number of tacos in x months will be given by
Equating the two equations, we get,
Thus, in 4 months Wyatt offer an equal number of sandwiches and tacos.
Answer:
7r³ - 3r² + 20r
Step-by-step explanation:
(9r³ + 5r² + 11r) + (-2r³ + 9r - 8r²)
You can get rid of the parentheses since there is nothing to distribute.
9r³ + 5r² + 11r - 2r³ + 9r - 8r²
Combine like factors.
7r³ - 3r² + 20r
Answer:
The bottom graph is the graph of that equation
Answer:
6.517%
Step-by-step explanation:
This is a multi-year investment and we are not working with a $1 initial investment. There is no mention of compounding so we will use formula A=P0⋅(1+r)N with A=$18,434 and P0=$14,320. We do not know the value of r. However, N=4 years. Substituting the values we have $18,434=$14,320⋅(1+r)4. Divide both sides of the equation by $14,320. Next, take the fourth root of both sides of the equation and subtract 1 to find the decimal form of r.
$18,4341.287291.065170.06517=$14,320⋅(1+r)4=(1+r)4=1+r=r
Finally, convert r to a percent.
r=0.06517×100%=6.517%
