A). 12 ÷ $7.20 = about $1.67 per muffin
b). 8 ÷ $4.40 = about $1.81 per muffin
c). 6 ÷ $4.50 = about $1.33 per muffin
type C costs the least per muffin
We let the number of years that the two jobs will have the same payment be denoted as t. Equating the wages of these two jobs after t - 1 years will give us an equation of,
22,000 + 4000(t -1) = 26,000 + 2000(t - 1)
The value of t from the generated equation is 3. Therefore, after 3 years the jobs will be paying the same wages.
Answer:
Quinzel sold 17 pairs of shoes last month.
Step-by-step explanation:
Let be "Q" the number of pairs of shoes Quinzel sold last month and "J" the number of pairs of shoes Joseph sold last month.
Set up a system of equations:
![\left \{ {{Q=J-18} \atop {Q+J=52} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7BQ%3DJ-18%7D%20%5Catop%20%7BQ%2BJ%3D52%7D%20%5Cright.)
Solve for "J" from the first equation:
![J=Q+18](https://tex.z-dn.net/?f=J%3DQ%2B18)
Applying the Substitution Method, you get:
![Q+J=52\\\\Q+(Q+18)=52\\\\2Q=52-18\\\\Q=\frac{34}{2} \\\\Q=17](https://tex.z-dn.net/?f=Q%2BJ%3D52%5C%5C%5C%5CQ%2B%28Q%2B18%29%3D52%5C%5C%5C%5C2Q%3D52-18%5C%5C%5C%5CQ%3D%5Cfrac%7B34%7D%7B2%7D%20%5C%5C%5C%5CQ%3D17)

Step-by-step explanation:
Rotation is a type of transformation referred to a in which the shape of the original object is preserved and the angle of rotation is constant for all the parts of the body.
Thus, when ΔDEF rotates 90° clockwise about point A to create ΔD 'E 'F.
