Answer 1

that way is:

6 $4
15 ?


4×15=60
60÷6=10

so answer is $10

Answer 2

STEP-BY-STEP SOLUTION:

Let x = cost of 15 tomatoes

6 tomatoes = $4

15 tomatoes = $x

Since the 6 from the first equation is multipled by 2.5 to obtain the 15 in the second equation, we must also do the same to the right-hand side of the equation.

This means we have to multiply 4 by 2.5 to obtain the value of x.

So:

x = 4 × 2.5

x = $10

ANSWER:

Therefore, the answer is:

The cost of 15 tomatoes is $10.
