Donna bought 3 pairs of pants for $28.50 each. She also bought a necklace for $12.25. She received a discount of 35% off her ent

oee [108]

Answer:

Donna will have to pay $67.985125 at the register, including the 7% sales tax.

Step-by-step explanation:

Donna bought 3 pairs of pants for $28.50 each.

So, the cost for 3 pair of pants $=(28.50\times 3)dollars= 85.50$ dollars.

She also bought a necklace for $12.25

Thus, the cost for her entire purchase will be: $(85.50+12.25) dollars = 97.75$ dollars.

She received a discount of 35% off her entire purchase. So, the amount of discount $=(97.75\times 0.35)= 34.2125$ dollars.

Thus, the total selling price will be: $(97.75-34.2125)= 63.5375$ dollars.

Percentage of sales tax is 7%. So, the amount of sales tax $=(63.5375\times 0.07)= 4.447625$ dollars.

Thus, the total amount Donna have to pay at the register $=(63.5375+4.447625)=67.985125$ dollars.

If three pears and four oranges cost $4.85 and three pears and ten oranges cost $8.75 what is the cost of a pear and an orange

marishachu [46]

Answer:

1 pear = $0.75; 1 orange = $0.65

Step-by-step explanation:

(1) 3P + 4O = 4.85

(2) 3P + 10O = 8.75 Eqn (2) - Eqn (1)

3P + 10O – 3P – 4O = 8.75 – 4.85 Combine like terms

6O = 3.90 Divide each side by 6

O = $0.65 Substitute into Eqn (1)

3P + 4×0.65 = 4.85

3P + 2.60 = 4.85 Subtract 2.60 from each side

3P = 2.25 Divide each side by 3

P = $0.75

Oranges cost $0.65 each and pears are $0.75 each
