Mrs. william shops at a store that has an annual membership fee of $30. today she paid her annual membership and bought several fruit baskets costing $15 each as gifts for her co-workers. her total was $105. solve the equation 15b+ 30=105 to find the number of fruit baskets mrs. williams purchased.

Number of fruit baskets purchased by Mrs. William is 5

Given that  

Annual membership fee of store where Mrs. William shops = $30

Cost of one fruit basket which Mrs. William as gifts for her co-workers = $15

Total amount spent by Mrs. William = $150

Given that "b" represents number of basket purchased

Equation which models the above scenario is as follows

15b+ 30=105   ------ (1)

Where b represents number of fruit basket purchased by Mrs. William

Need to calculate number of fruit basket purchased by Mrs. William

For which we need to solve equation (1) for b  

On solving we get

15b+ 30 = 105    

On Subtracting 30 from both sides we get

15b + 30 – 30 = 105 – 30

=> 15b = 75

On dividing both sides by 15 we get  

As variable "b" represents number of basket purchased, hence we can conclude that number of fruit baskets purchased by Mrs. William is 5

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
