$$7.5 \times 22 + 2.5 \times 7 + 2.5 \times 6 + 7.5 \times 23 =$$

Evaluate

$$370$$

Solution Steps

Multiply 7.5 and 22 to get 165.

$$165+2.5\times 7+2.5\times 6+7.5\times 23$$

Multiply 2.5 and 7 to get 17.5.

$$165+17.5+2.5\times 6+7.5\times 23$$

Add 165 and 17.5 to get 182.5.

$$182.5+2.5\times 6+7.5\times 23$$

Multiply 2.5 and 6 to get 15.

$$182.5+15+7.5\times 23$$

Add 182.5 and 15 to get 197.5.

$$197.5+7.5\times 23$$

Multiply 7.5 and 23 to get 172.5.

$$197.5+172.5$$

Add 197.5 and 172.5 to get 370.

$$370$$

Factor
