At a skateboard shop: a) The price tag on a shirt says $12.58. Sales tax is 7.5% of the price. How much will you pay for the shirt? Show your work

b) The store buys a helmet for $19.00 and sells it for $31.50. What percentage was the markup? Show your work

c) The shop pays workers $14.25 per hour, plus 5.5% commission. If someone works 18 hours and sells $250 worth of merchandise, what is the total amount of their paycheck for this pay period? Show your work

a= 7.5%12.58= 0.9435 round 0.94+12.58= 13.52

b= 31.50 divided by 19.00= 1.65789474 round 1.66

c= (14.25 x 18)+ (5.5%250)

        256.50 +   13.75 =  270.25

Step-by-step explanation:

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.

ok
