You are a contractor and charge $45 for a site visit plus an additional $24 per hour for each hour you spend working at the site. write and solve an equation to determine how many total hours you have to work to earn $765 working at a work site

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
