A company manufactures skateboards. Each skateboard requires 1 6/7 hours of labor to assemble and 2 1/2 hours of labor to finish
Assoli18 [71]

Answer: The total cost will be $156.85.

Step-by-step explanation:

Since we have given that

Time taken by labor to assemble the each skateboard is given by

1\frac{6}{7}\ hours\\\\=\frac{13}{7}\ hours

Time taken by labor to finish and stain each skateboard is given by

2\frac{1}{2}\ hours\\\\=\frac{5}{2}\ hours

Cost of labour to the company per hour = $36.00

According to question,

We will use "Distributive Property":

a\times (b+c)=a\times b+a\times c

36(\frac{13}{7}+\frac{5}{2})\\\\=36\times \frac{13}{7}+36\times \frac{5}{2}\\\\=\frac{468}{7}+18\times 5\\\\=\frac{468}{7}+90\\\\=\frac{468+630}{7}\\\\=\frac{1098}{7}\\\\=\$156.85

Hence, the total cost will be $156.85.

bija089 [108]
2x - 13 = 33 \\ 2x = 33 + 13 \\ 2x = 46 \\ \frac{2x}{2} = \frac{46}{2} \\ x = 23
33-23=10. 10+23=33. 23-10=13
the numbers are 23 and 10
