Answer:
2f+2y+pd+z(d+2)
Explanation:
If Brandon buys 2 gifts and the cost of each gift is f, then the cost of the 2 gifts is 2f.... 1
Also if Daniel buys d gifts, the cost of each gift is p, then the cost of d gifts will be "pd ".... 2
If Georgia buys 2 more gifts than Daniel, then the amount of gift bought by daniel will be d+2. If the cost of each gift is z, the cost of (d+2) gifts will be z(d+2) .... 3
If Mr. Jones also decides to buy gifts for his children and the cost of each gift is f, then the total cost of the gift he bought for his children is yf where y is the number of gifts he bought for his children.
The total amount paid by Mr. Jones will be expressed by the summing all the derived function as shown;
2f+dp+z(d+2)+yf
= 2f+yf+ dp+z(d+2)
= 2f+2y+dp+z(d+2)
Hence the algebraic expression for how much money Mr Jones should pay at the gift shop till if he also decides to buy gifts for his children and the cost of each gift is f is expressed as 2f+2y+dp+z(d+2)
