AND PLEASE SHOW WORK 1. 20% OF = 40 2. 30% OF =90

1. 200, 2. 300

Step-by-step explanation:

40 * 10/2 = 400/2 = 200

or this way:

40 = 20%

40/2 = 20

20 = 10%

20 * 10 = 200

——————————————

90 * 10/3 = 900/3 = 300

or this way:

90 = 30%

90/3 = 30

30 = 10%

30 * 10 = 300

1. 200

2. 300

Step-by-step explanation:

1.

20% = 20/100 = 0.2

20% OF = 40

0.2 * x = 40

x = 40/0.2 = 20

2.

30% = 30/100 = 0.3

30% OF =90

0.3 * x = 90

x = 90/0.3 = 300

The picture frame costs 4 times as much the calculator. We know that the calculator costs $12 so

4 x 12 = $48 is what the picture frame costs

12 / 3 = $4 is what the toy is.

In total she payed

12

48

 4    +

= $64
