JACQUI AND JOAN BOTH DONATED MONEY TO THE
SAME CHARITY. JACQUI GAVE THREE TIMES AS MUCH
AS JOAN. THEY DONATED A TOTAL OF $280. HOW MUCH
DID JACQUI DONATE?"

$210

Step-by-step explanation:

X - the amount of money given by Jacqui

Y - the amount of money given by Joan

1. Jacqui gave three times as much as Joan so:

X = 3 * Y

2. Together they gave $280 so:

X + Y = $280

3. Now we replace X by 3 * Y then:

3 * Y + Y = $280

4 * Y = $280

Y = $70   - now we know how much Joan donated

4. Jacqui donated three times as much so we just multiply it:

X = $70 * 3

X = $210   - this is the final value

2/5

step-by-step explanation:

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
