Keith buys 3 kiwis and 4 zucchini's for a total of $4.95. A Kiwi costs $0.25 more than a zucchini. What is the cost of 1 kiwi and 1 zucchini?
Let the price of a zucchini = Z
Then....let the price of a kiwi = Z + .25
And we know that
3 (Z + .25) + 4(Z) = 4.95 simplify
4Z + 3Z + .75 = 4.95 subtract .75 from both sides
7Z = 4.20 divide both sides by 7
Z = .60 = the price of a zucchini
Z + .25 = .85 = the price of a kiiwi
Let's make Z the price of a zucchini, and Z + 0.25 the price of a kiwi.
We know that 3(Z + 0.25) + 4 * Z = 4.95.
If we simplify the equation: 3Z + 0.75 + 4Z = 4.95.
Subtracting 0.75 from both sides: 7Z = 4.20
Z = 0.6 which is the price of a zucchini
Z + 0.25 = 0.85 which is the price of a kiwi.
Which is what CPhill got!
