The amount of money Sandy spent on pears is 4

pcents, or, since 1 cent is 1/100 of a dollar, dollars.The amount of money Sandy spent on oranges is $8. (She bought 6 oranges; 3 oranges cost $4.)

In all, Sandy spent dollars.

If she wants to spent this money on 7 mangoes, each mangoe must cost this amount divided by 7:

Each mango costs dollars.

Wait. I dont get it. Why are you multiplying 8*25. And why are you multiplying 25*7?

She multiplied the whole term by (25/25) to clear the denominator. This is allowed because it is essentially multiplying the term by 1, thus not changing it.

Notice that (p/25) was multiplied by 25 to yield just p. 8 was multiplied by 25 and 7 was multiplied by 25 as well as another part of the process of multiplying the whole term by 25.

The amount of money Sandy spent on pears is 4*p *cents, or, since 1 cent is 1/100 of a dollar, `4p/100 = p/25` dollars.

The amount of money Sandy spent on oranges is $8. (She bought 6 oranges; 3 oranges cost $4.)

In all, Sandy spent `8+ p/25 ` dollars.

If she wants to spent this money on 7 mangoes, each mangoe must cost this amount divided by 7:

`(8+p/25)/7= (8*25 + p)/(25*7)=(200+p)/175`

**Each mango costs `(200+p)/175` dollars.**
