Question

Johnny bought candy for 69 cents per ounce. He spent $3.50. How many ounces of candy did she buy?

Answer 1

`5 5/69` ounces

Explanation:

`$3.50 div ($0.69)/("ounce")`

`color(white)("XXX")=cancel$3.50 xx (" ounce")/(cancel$0.69)`

`color(white)("XXX")=350/69 " ounces"`

`color(white)("XXX")=5 5/69 " ounces"`

Answer 2

`~~5` ounces

Explanation:

If `1` ounce `= 69` cents

Then `?` ounces `=3.50` cents

If `$0.69` (which is less than `$3.50`) gives `1` ounce, then we should get more ounces for `$3.50`.

If more, less divide.

`:.(cancel($)3.50)/(cancel($)0.69) xx 1` ounce

`rArr5.07` ounces
