Which expression can Dawn use to calculate the total price for her purchase?
A.(45 + 29) • 0.40 + 59 • 0.25
C.(45 + 29 + 59) • 0.65
B.(45 + 29) • 0.60 + 59 • 0.75
D.(45 + 29 + 59) • 0.35

Answer 1

Option C

The expression can Dawn use to calculate the total price for her purchase is:

$Total\ purchase\ price = (45+29) \times 0.60 + 59 \times 0.75$

Solution:

From given,

Discount for sandal = 40 % off

Discount for sneakers = 25 % off

Dawn purchases a pair of sandals with a regular price of $45 and another pair of sandals with a regular price of $29

Discount for sandal = 40 % off

If discount is 40 %, then they have to pay the 60 % amount

Therefore,

purchase price = 60 % of $ 45 + 60 % of $ 29

purchase price = 60% (45 + 29)

$Purchase\ price = 60 \% \times (45 + 29)\\\\Purchase\ price =\frac{60}{100} \times (45+29)\\\\Purchase\ price = (45+29) \times 0.60$

A pair of sneakers with a regular price of $59

Discount for sneakers = 25 % off

If discount is 25 % off, then they have to pay 75 % amount

Therefore,

Purchase price = 75 % of $ 59

$Purchase\ price = 75 \% \times 59\\\\Purchase\ price = \frac{75}{100} \times 59\\\\Purchase\ price = 59 \times 0.75$

Find the Total price of purchase:

$Total\ purchase\ price = (45+29) \times 0.60 + 59 \times 0.75$

Thus Option C is correct
