Answer 1

Given

Frankie is helping his mother make a fruit salad.

The sign shows the prices for the three kinds of fruit he needs for the fruit salad,

Bananas: 3 for $0.99

Oranges: 6 for $1.50

Peaches: 4 for $1.28

And his mother tells him that they need 5 bananas, 15 oranges, and 10 peaches for the salad.

To determine the total cost for the amount of fruit that Frankie needs.

Step-by-step explanation:

It is given that,

Bananas: 3 for $0.99

Oranges: 6 for $1.50

Peaches: 4 for $1.28

That implies,

`\begin{gathered} Cost\text{ }of\text{ }1\text{ }banana=(0.99)/(3) \\ Cost\text{ }of\text{ }1\text{ }banana=(1.50)/(6) \\ Cost\text{ }of\text{ }1\text{ }peach=(1.28)/(4) \end{gathered}`

Therefore,

`\begin{gathered} Total\text{ }cost=5*(0.99)/(3)+15*(1.50)/(6)+10*(1.28)/(4) \\ =1.65+3.75+3.2 \\ =8.6 \end{gathered}`

Hence the total cost is $8.6.
