Amy earns a weekly paycheck consisting of base pay of $225, plus a commission of 4.8% of her weekly sales.

(a) Write an equation that can be used to determine Amy’s weekly paycheck P, given the amount of weekly sales s.

(b) Determine Amy’s weekly paycheck if her weekly sales are $15,420.

a) P = 225 + .048(s)

b) just plug in 15420 for s and evaluate.

so based on this her sales would be

$740.16 money earned from weekly sales
+225.00 base pay
$965.16 Amy’s Weekly Paycheck Earnings

(a) To determine Amy's weekly paycheck, we need to add her base pay of $225 to her commission, which is calculated at 4.8% of her weekly sales.

Let's break it down:

Base pay: $225
Commission: 4.8% of weekly sales

To calculate the commission, we multiply the weekly sales by 4.8% (in decimal form, 0.048). Let's call the commission C and the weekly sales s:

C = 0.048 * s

To determine Amy's weekly paycheck, P, we add her base pay and commission:

P = Base pay + Commission
P = $225 + C

Now, substitute the value of C:

P = $225 + (0.048 * s)

(b) To determine Amy's weekly paycheck when her weekly sales are $15,420, we can substitute s with $15,420 in the equation we derived in part (a):

P = $225 + (0.048 * $15,420)
P = $225 + $741.60
P = $966.60

Therefore, Amy's weekly paycheck will be $966.60 when her weekly sales are $15,420.
