Help with part B.

Corinne has a job selling magazines. She earns $7.50 per hour plus 20% of the total amount of her sales. She also gets an allowance of $40 per week for gas. She knows her weekly earnings can be shown using the following expression:

7.50h + 0.20s + 40
Part B: If Corinne works for 25 hours and sells $300 in magazines, how much does she earn for the week? Show your work to receive full credit. (4 points)
Is it (25*7.50)+(0.2*300)+40=187.5+60+40=187.5+100= 287.5

np and yes, that's how you would right it out
replace "h" with 25 and "s" with 300

tanya123 · Answer

To solve this plug in 25 into "h" in and 300 for "s" in the equation 7.50h + 0.20s + 40 and then solve.
1. 25 * 7.50 = $187.5. 
2. 0.20 * 300 = $60
3. Add it all together: $187.50 + $60 = $247.50 + $40 = $287.50
