Answer:
B = 140.
Explanation:
The amount of money (b) is 140, to find what number divided by 20 that equals $7.00 we have to multiply 20 times 7, why? multiplying the times divided will give the same answer you´re looking for (20 x 7). Which equals 140, then if you divide 140 by 20 (140÷20). Will equal to 7.
Hope this helps.
