Rebekah's baby brother weighs 7.71 pounds. how much more than 10 pounds will her baby brother weigh if he gains 1.3 pounds each week for the next 2 weeks?

.31 lbs

Step-by-step explanation:

1.3 lbs per week x 2 weeks = 2.6 lbs

2.6 + 7.71 = 10.31 lbs

0.31 pounds

Step-by-step explanation:

Rebekah's baby brother weight = 7.71 pounds

If he gains 1.3 pounds each week for the next 2 weeks

Then his new weight;

= 7.71 + (1.3 × 2)

= 7.71 + 2.6

= 10.31 pounds

Compared to 10 pounds,

= 10.31 pounds - 10 pounds

= 0.31 pounds

It means that in two weeks time if the baby gains 1.3 pounds each week, the baby will weigh 0.31 pounds more than 10 pounds.
