Answer:

A. 282

Step-by-step explanation:

A trick I know is if you add all the digits of the number and they add up to a multiple of 3, it is divisible by 3.

282:

2 + 8 + 2 = 12

187:

1 + 8 + 7 = 16

385:

3 + 8 + 5 = 16

412:

4 + 1 + 2 = 7

Write as an equation: Sara spent $2 more than Lauren, and together they spent $19.

kupik [55]

Answer:

Equations:

a + b = 19

a = b + 2

a = Money that spent Laura

b = Money that spent Laureen

then:

(b+2) + b = 19

2b + 2 = 19

2b = 19-2

2b = 17

b = 17/2

b = 8.5

a = b + 2

a = 8.5 + 2

a = 10.5

Check:

10.5 + 8.5 = 19
