Answer: Priya enjoyed a 40% discount
Step-by-step explanation:
The key information in the question:-
*** The normal cost of a pair of earrings is $22
*** Priya eventually purchased the pair of earrings for only $13.20
*** We are required to calculate the percentage discount.
Discount generally refers to the reduction from the usual price of something. In this scenario, since Priya bought the pair of earrings for only $13.20 instead of the usual $22, the discount that Priya enjoyed =
$22.00 - $13.20
= $8.8
To calculate the percentage discount that Priya enjoyed, we divide the discount by the normal price and then multiply the result by 100
= (8.8/22) × 100
= (88/220) × 100
= 0.4 × 100
= 40%
Therefore, Priya enjoyed 40% discount on the price of the pair of earrings.
Since there are 14 boys and the whole class has 31 students
We get, the ratio of the part-to-whole relationship for boys is 14/31.
And since there are 17 girls
We get, the ratio of the part-to-whole relationship for girls is 17/31.
We have the height h(t) as
h(t) = -16t² + 1024
16t² is how far we've fallen as a function of time; since we started 1024 feet up the height is 1024-16t².
Answer: the distance the brush falls in t seconds, first choice
t + c = 32
0.80 t + 0.40 c = 18
Multiplying the first by 0.8
0.8 t + 0.8 c = 0.8 (32) = 25.6
Subtracting,
0.8 c - 0.40 c = 25.6 - 18
0.40 c = 7.6
c = 7.6/.4 = 19
Answer: 19 cans of corn
Check
t = 32-19 = 13
.8(13)+.4(19) = 18 good
