Blue model

10 total

Step-by-step explanation:

80% of Tom's tie-dye shirts have a spiral.

8 of his tie-dye shirts have a spiral.

80% = 8

In the blue model, the number of shirts, 8, is under the 80%.

To find the number of shirts Tom has, find out how many shirts each block represents in the model.

Each block is 20%. There are 4 blocks up to 8 shirts.

Divide the number of shirts by the number of blocks.

8 shirts ÷ 4 blocks = 2 shirts per block

100% means the total number of tie-dye shirts.

To get to 100%, there is one block left.

Add 2 shirts to 8.

8 + 2 = 10

∴ Tom has 10 tie-dye shirts in total.

Total number of shirts = 10

First model represent the problem.

Step-by-step explanation:

Let,

Total number of shirts = x

According to given condition;

80% of x = 8

(80/100)x = 8

x = (8×100)/ 80

x = 10

Total number of shirts = 10

First model represent the problem.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
