Question

William had $45 dollars to spend on vegetables. After buying 6

watermelons, he had $25.50 left. How much did each watermelon cost?

Answer 1

They each costed around $3.25 each!

Answer 2

Let the cost of one watermelon be 'x'.

Amount of money spent by William on vegetables = $45

Number of watermelons bought by William = 6

Amount left with William = $25.50

Equation will be,

45 - 6x = 25.50

Add -45 on both sides,

45- 45 - 6x = 25.50 -45

-6x = - 19.50

Divide both side by -6 to find the value of x

`(-6x)/(-6)`=
`(-19.50)/(-6)`

x=
`(-19.50)/(-6)`

x = 3.25

So the cost of each watermelon is $3.25
