Answer:

Step-by-step explanation:

Cost of game = $120

Current savings = $30

Rate for babysitting (per hour) = $5/hour

So, required equation is :-

120 = 5h + 30

5h = 90

h = 18

She must make $90 by babysitting for 18 more hours.

Kisachek [45]

Answer:

$24-4x$

Step-by-step explanation:

We have been given that Niu has decorated x cards. He started with 24 stickers and he used 4 stickers per card. So stickers used in x cards will be 4x.

As initial number of stickers was 24, so we can find number of stickers left after decorating x cards by subtracting number of stickers used in x cards from 24.

$\text{Number of stickers that Niu has left}=24-4x$
