stich3 [128]

Answer:

Carl has to sell at least $8$ cookies.

$c\geq 7.5$

Step-by-step explanation:

Carl gets $\$1.50$ by selling 1 chocolate bar.

Earning from chocolate bars:

$Total\ chocolate\ bar=20\\\\Earning\ from\ one\ chocolate\ bar=\$1.50\\\\Total\ earning\ from\ chocolate\ bar=Total\ chocolate\ bar\times cost\ of\ 1\ chocolate\ bar=20\times 1.5=\$30$

Earning From cookies:

$Let\ total\ number\ of\ cookies=c\\\\Cost\ of\ 1\ cookie=\$2\\\\Earning\ from\ cookies=2\times c=2c$

$Total\ earning=Earning\ from\ cookies+Earning\ from\ cookies+Earning\ from\ chocolate\ bars\\\\Total\ earning=30+2c$

Carl wants to raise at least $\$55$

$Total\ earning\geq 55\\\\2c+30\geq 55\\\\2c\geq 55-30\\\\2c\geq 15\\\\c\geq7.5$
