24% of 38 = (1 - 24/100) × 38 = 28,88 = 29

24 % ←→ 29
x% ←→ 10

x = 10 × 24 ÷ 29
x = 8,27586
x = 8 %

ANSWER 8%

AleksAgata [21]

Answer:$920

Step-by-step explanation:

Since the variation is joint, I=KPr where k is the constant of proportionality.

Plugging in the values of I=$375, P=$1500 and r=5% in the equation I=KPr, the value of k can be calculated. Hence, the formula connecting the three quantities (I,P and r) can be generated.

375 = K (1500×5)

Making k the subject of change,

K = 375/(1500×5)

K=1/20

Formula connecting the three quantities :I =Pr/20

when P=$2300, r=8%,

I = (2300×8)/20

I = $920
