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.
Explanation:
It is given that,
Bananas: 3 for $0.99
Oranges: 6 for $1.50
Peaches: 4 for $1.28
That implies,
[tex]\begin{gathered} Cost\text{ }of\text{ }1\text{ }banana=\frac{0.99}{3} \\ Cost\text{ }of\text{ }1\text{ }banana=\frac{1.50}{6} \\ Cost\text{ }of\text{ }1\text{ }peach=\frac{1.28}{4} \end{gathered}[/tex]Therefore,
[tex]\begin{gathered} Total\text{ }cost=5\times\frac{0.99}{3}+15\times\frac{1.50}{6}+10\times\frac{1.28}{4} \\ =1.65+3.75+3.2 \\ =8.6 \end{gathered}[/tex]Hence the total cost is $8.6.
