Ryan worked for 7 hours and earned $52.50. If this rate increased by 4%, what will he earn if he works for 8 hours?

$62.40

Step-by-step explanation:

7 hours of work: $52.50

1 hour of work:

$52.50 / 7 = $7.5

$7.5 per hour

If Ryan's rate increased by 4%, what would he earn per hour?

$7.5 * 1.04 = $7.8

New hourly wage: $7.8 per hour

For 8 hours of work:

$7.8 * 8 = $62.4 = $62.40

$62.40

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
